Constantly from foreign leaders about some of the wackier suggestions that are being made. I do have to emphasize, its not just mr. Trumps proposals. You are also hearing concerns about mr. Putins proposals, which in some ways are just as draconian when it comes to immigration, for example. The implications, with respect to ending remittances which by the way are many are from legal immigrants and individuals who are sending money back to their families, are enormous. First of all, they are impractical. We just talked about the difficulties of trying to enforce outflows of capital. The notion we are going to track every western union, you know, bit of money thats being sent to mexico, you know, good luck with that. Then weve got the issue of the implications for the mexican economy, which in turn, if it is collapsing, actually sends more immigrants because they cant find jobs back in mexico. This is just one more example of something that is not thought true and primarily put forward for political consumption. As ive tried to emphasize throughout, we have Serious Problems here. We have big issues around the world. People expect the president of the United States and the elected officials in this country to treat these problems seriously, to put forth policies that have been examined and, analyzed, are effective, where unintended consequences are taken in to account. They dont expect halfbaked notions coming out of the white house. We cant afford that. Halfbaked notions coming out of the white house. Lets get analysis and reporting on what we just heard. Jim acosta is standing by. Our White House CorrespondentMichelle Kosinski is with us and alison kosik is with us as well. Michelle, you were in the white house when the president came out, not only speaking about donald trump on his own but brought ted cruz in the equation as well. He is increasingly speaking his mind about the national security, Foreign Policy views of these republican president ial candidates. Even some of the words and phrases. Half baked and wacky, hitting not just trump even though that is what the question was about but also cruz. In the beginning he didnt want to get involved. He was being diplomatic in the way he would phrase things. He would lump everybody in and not get specific. Now he is more free wheeling in the way he responds. He says whenever he speaks to World Leaders this is what comes up. I thought what is interesting, the white house for a long time talk ed about this rhetoric among the republican candidates. Aly doing damage to the u. S. s stachbding in the world calling it harmful potentially to national security. We asked the white house has some of that damage already been done in your opinion . Because the white house keeps talking about that. And the press secretary said no. I dont think the damage what been done yet. Today when the president was asked that question he immediately and unequivocally said yes. Wolf . Stand by. I want to bring in jim acosta whos been on the campaign trail reporting for us. Jim, the Trump Campaign, im sure the cruz campaign, will probably not waste time in reacting to what we heard from the president. I think that is right, wolf. I think they welcome the comments from president obama quite frankly. Youll recall a couple of months ago, when i have sen stay fox weighed in on how he thinks that mexico would never pay for a wall on the u. S. Mexican border and donald trump used it at Campaign Stop after campaign stap stop. This is Donald Trumps reaction to months of criticism from people insided the beltway sighing you dont have a proposal for paying for the wall on the Mexican Border and this is the Trump Campaign saying here it is. It is worth reminding our viewers one of the top surrogates for donald trump is Jeff Sessions from alabama, fierce antiimmigration advocate and one of Jeff Sessions top aides, the top policiedy advise for Donald Trumps campaign. Not a huge surprise you heard the president go after the practicality of this. But i have to tell you from talking to people inside the Trump Campaign they feel this is feez able and you heard trump say that earlier this morning at a Campaign Stop here in wisconsin. Heres what he had to say. Self explanatory. It is a fraction of the money in different ways that mexico takes in from the United States. A fraction. 10 billion wall. You are talking about a trade deficit with mexico 58 billion and probably going to get worse if they run it. If i run it there wont be a trade deficit. So a couple of things here with donald trump putting out the proposal. We are not talking about the messy leak over the last several days with his Campaign Manager and his comments on abortion and so fort and so on or the wall proposal and yes, this is getting everybody to talk about this. The key in milwaukee, wisconsin, other midwestern states people like the economic populous message than is something donald trump hopes will help him later at the ballot box later on today. If he can eke out a victory that would have a huge impact on the campaign. Alison kosik you are with us as well. The president made the comments in response to a question but he came in the Briefing Room at the white house to announce Treasury Department regulations to prevent American Companies from setting up headquarters overseas to avoid paying taxes. Explain what the president is now proposed . Okay. So what the president proposed here is something that congress hasnt done yet. It is why we see the u. S. Treasury stepping in with new regulations, trying to close loopholes that companies have been using to especially move headquarters overseas to avoid paying a higher tax rate. The u. S. Has the highest tax rate at 35 . To give you an example, in ireland the tax rate is 12. 5 . Wa we have seen for many years now is we are seeing companies merging with other companies or moving their headquarters overseas so they can avoid paying the higher tax rate. If they make a profit overseas, the American Company and they want to bring it back to the u. S. They have to pay a total of 35 in that Corporate Tax rate. You are seeing the administration stepping in because what it means is the tax rolls are losing anywhere from 100 billion to 240 billion per year in tax revenue because these companies are moving their headquarters overseas and not paying the u. S. Their taxes. Case and point, a couple of years ago, burger king took over tim hortons. Burger king moved their haerks to canada. They said it was a growth issue and not a tax issue. They are dodging one whopper of a tax bill, more than 400 million a year that burger kichk is avoiding paying in u. S. Taxes now it moved the headquarters. Not just burger king, a lot of american a companies are taking advantage of what the president called a tax loophole. This loophole he calls corporate inversion. Thats what a lot of people are calling it. Interestingly enough, donald trump keeps talking about he will deal with the corporate inversion problems, as well, if he becomes the president of the United States. Jim acosta, he speaks about corporate inversion in almost all of his stump speeches, doesnt he . He does. This is one of those issues where donald trump and president obama are 0 almost on the same page. But if you were to ask either side of the equation they would disagree with that. Donald trump, this is one of his messages on the economy. He accuses corporations all the time of stashing their headquarters overseas so they can avoid paying taxes. Absolutely. This is something that donald trump says he will do if he is elected president. He will rewrite trade rules and trade pacts with china, mexico and so forth. Absolutely. On the tax inversion issue, its interesting to see donald trump and president obama on the same page here. The president points out in his statement that for three budgets in a row hes tried to get congress to eliminate the corporate inverges but he has failed. Congress has not done so. He is hoping the department of treasury regulations will get the job done. Thank you very much. Right now the polls are open in wisconsin. Voters are deciding what could be a major race on both sides. At stake, momentum. Delegates an the chance of a contested convention, not only on the republican side, but if you listen to Bernie Sanders supporters on the democratic side, as well. Drak.

Voting now underway in the wisconsin primary and the results could have major implications in the erase for the white house. The republican president ial front runner donald trump sounding confident during a stop at a diner earlier today. The poll s are busy, huh . They are busy. We could have a big surprise tonight, folks. Big surprise. Trump hopes to resume his march toward the nomination, but ted cruz is banking on a win to stop trumps momentum. John kasich is trying to hang on until the convention despite calls by trump and cruz to drop out. 42 delegates are at stake for the democr the democrats. Sanders is trying to build on his winning streak and the Clinton Campaign points to her lead in the race. They are competing for 86 delegates up for grabs. Sanders says momentum is on his side and he says clinton is getting nervous. So dont tell her this, but i think we will win here and new york state and we are on the way to the white house. If there is a recordbreaking turnout in wisconsin he will win. For a look at how it is going lets check in. Polling place in green bay, wisconsin give us a sense of what you are seeing and hearing from the voters. Both Bernie Sanders and Hillary Clinton made the case that if turnout is high they will do well here. Good fuse for both of those campaigns, turn out is high in the polling place where we are in green bay. 400 people have come through since 7 00 a. M. It usually gets 1600 and they expect more than that today. I talked to some of the voters here and voters say they are going for Bernie Sanders. I talked to one republican who said he crossed to the democratic side to vote for Bernie Sanders because hes a never trump guy. In wisconsin it is an open primary. You can choose whether to go republican or democrat. That is good news for Bernie Sanders as he tries to run up the score in hi wisconsin. Hillary clinton has been lowering expectations here in this state all week long pointing out the state is one she lost to then senator barack obama in 2008 by doubledigits. It is more white than average state, which always helps Bernie Sanders. Hillary clinton already kind of moving on to new york. She was on the view. She tried to make a stand. 250 delegates at stake on april 19th. Second only to california. Shes trying to make sure she holds a doubledigit lead she has against Bernie Sanders. Of course Bernie Sanders looking to do well here today in wisconsin and take the momentum to the empire state, cutting in to Hillary Clintons lead. Hes down by 240 delegates and he needs 75 of the pledged delegates left to clinch that nomination. Hillary clinton only needs 35 . The next big day on the primary calendar after today of course april 14th. That is five days before the crucial empire state primary where Bernie Sanders and Hillary Clinton will go one on one here on cnn with a big debate in brooklyn. Thats the first time we have seen those two go head to head in more than a month. We will look forward to that and see if Bernie Sanders gets the bounce hes hoping for out of wisconsin. Wolf . We look forward to that debate a week from thursday in well be right back lynn. Thank you very much. A look at what is at stake for the candidates right now. Joining us, cnn political reporter and cnn political commentator, washington correspondent for the new yorker magazine. How important is tonight for donald trump if he were to lose wisconsin does that make a possibility of a contested convention in july more likely . It does. Obviously his hope is to pick up some delegates tonight. Hes talking about his po penn tenial surprise. I dont know if we will see that. What is interesting is that in another brilliant tactical move today by putting out another piece of his wall plan that he has talked about in the past. We are all talking about that instead of his horrible week last week with his abortion comments ante back and forth. So it is yet another reminder of how well donald trump does in changing the subject when it is not working in his favor. Ted cruz has a good operation in wisconsin. Obviously the antitrump forces are in there trying to help boost ted cruz to victory. And we will see what happens tonight. What could also happen and maybe this explains in part why donald trump seems to be so up beat that he may win in wisconsin it is an open contest. Meaning independents, democrats can crossover. They can vote on the republican side. Thats been a source of big support for him. By the way, also a big support for Bernie Sanders. Who also appeals to the nontraditional Democratic Base if you will. I think that is a good point. That along with the fact we have seen a lot of primary polling that has not been accurate. It means we should be cautious about how much ted cruz has put this away. I would be looking tonight for the delegate margin, not so much thats the number you want to know, how many delegates does ted cruz win. At the end of the night, you want to know the percentage of remaining delegates that donald trump will need to get to that magic number to win the nomination with the majority of delegates. Hes going in to this race tonight having won less than 50 of the total delegates so far. Needing to win somewhere in the mid 50s, 54 , depending on the count of the remaining delegates. If ted cruz wins the majority of the 42 up for grabs tonight, trump has to win close to 60 of the remaining delegates Going Forward from now until june 7th. He won less than 50. So hitting 60 is a tall order. If ted cruz has a big night tonight, the story will be that most projections will say that donald trump will come up short and we will go to a contested convention. Big night, big Tipping Point for the race tonight. Maeve, the campaign nrg for the hillary Clinton Campaign wrote a memo saying Hillary Clintons delegate lead insurmountable and he said sanders path to the nomination involves a combination of flipping pledge delegates an convincing super delegates he deserves their support despite the fact that hillary won 58 of the popular vote and the majority of pledged delegates thus far. What do you think of his argument . I think he is right. The math very clearly is on Hillary Clintons side. Bernie sanders has a huge uphill task going in to the upcoming primaries. Tonight in wisconsin, of course i will the delegates are proportional. They may both end up creeping up some. Bernie sanders needs a strong night tonight in wisconsin for momentum purposes. Purely for momentum purposes. Hes been talking about how his campaign has extraordinary momentum, winning rekren contests a he is hoping if they win tonight they can zoom in to new york, other or and california with the wind in their sails. So hes got a lot on the line. If he does not do well tonight, this race will really look like it is winding down. At the same time, theres so much energy on his side. Hes cleaning up in terms of those Campaign Donations and obviously that is frustrating the Clinton Campaign. Thank you very much. Democratic National Committee chair Debbie Wasserman schultz will join us life. We will talk about the race and whats at stake for the Democratic Party and the next democratic president ial debate.
