A lot of people want to stop you. Are they succeeded . I dont know if the worse week of my campaign. Ive had many good weeks and many bad weeks and i dont see this as the worst week of my campaign. Youve been reporting on some weeks that was the end. The next week you see poll numbers where they went up and everybody is shocked. Yeah, people want to stop me because im leading by a lot. The new polls that came out have me leading by more than ever. Nbc had a very Good National poll that just came out. I guess im leading very big in new york and pennsylvania. Let me ask you about abortion. What would you do to further restrict womens access to abortion as president . Look. Look. Youre going and i just want to say a question was asked to me and it was asked in a very hypothetical and it was said, illegal, illegal. Ive been told by some people that was an older line answer the basis of an older line from years ago, on a very conservative basis. But your original answer, you mean . My original answer. But i was asked as a hypothetical hypothetically. Hypothetically. The laws are set now on abortion and that is the way they are going to remain until they are changed. Because you had said you told bloomberg in january that you believed abortion should be banned at some point in pregnancy. Where would you first of all, i would like to see this be a states rights. I think it would have been better if it were up to the states. But right now, the laws are set and that is the way the laws are. But you have a feeling how a lot of laws you want to change and youve talked about them from libel to torture. The laws are set and i think we have to leave it that way. Do you think murder is abortion . I have my opinions on it but rather not comment. You said you were pro life. Abortion is murder . I do have my opinions on it. Id rather i just dont think its an appropriate forum. But you disagree with that proposition that its murder . What proposition . That abortion is murder. No, i dont disagree with it. Searching for further clarity on trumps comments to us. His campaign released a Statement Last night saying, quote, mr. Trump gave an accurate account of the law as it it is today and made clear it must stay that way now, until he is president.

Lets take a closer look at the president ial campaign. We are joined by phillip bump, a reporter for the washington post. Good morning. We heard earlier donald trump say this was not his best week or worse week. If he should lose wisconsin, what happens . The problem for donald trump is, you know, again, he is not running against ted cruz or john kasich. He is running to see if he can get the delegates he needs to be the nominee. For him to win those delegates. A lot of states are winner take all or most. The winner of the state will get most of the delegates and that is the case in wisconsin. Looks like he go inc. To lose wisconsin and looks fewer delegates to add to the total and not the path he needs to be on. He had a meeting with the Republican Party on thursday. Right. What was essentially going down there . Well, he has been he has been frustrated because the way the Convention Works there is all of these delegates from all of the different states and they have different rules how they are apportioned. Louisiana, in particular, irritated him because he won the state and probably come out with fewer delegates because ted cruz is better about working the rules. Went to the rnc in part to complain about that but i think also to try to convince them to coalesce around him finally, which they are still reticent to do. What if he doesnt have the majority of delegates by then, what will happen . Once he gets to the convention, there are a series of votes and there is a committee called the rules committee which decides how a lot of power how the process works. The party not big fans of donald trump but there will be a vote. After the first vote whatever pledge delegates he has some of them are not pledged to them and they can vote for whoever they want to. Ted cruz has done a good job organizing to get delegates who support him and even though go to the convention and have to vote for trump on the first vote if cruz is on a second or third vote, they will vote for him. Do you think the partys efforts to slow or stop trump were helped this week greatly . I think so. I think the abortion comments that trump made was primary he made himself look he wasnt sure what the answer should be. So i think that provided fodder to the never trump people because they are able to say, look. This guy isnt prepared for this. If he loses wisconsin which it looks like he will i think goes forward in another step. This week we watched Bernie Sanders attack Hillary Clinton and fossil fuel energy and the money she has related to. How effective is that strategy for him . I think effective from the standpoint that sanders needs wing of the democratic party. He really needs them to come out. He needs to position himself as being the more leb ral candidate which liberal candidate and he has been successful and more to vote against Hillary Clinton. I think its murky than he portrays it and i think its effective to the standpoint that reminds people Bernie Sanders is the progressive candidate in this race. Phillip wumpbump. Every time you think it cant get more interesting, it.
