Two president past and present on the campaign trail ahead of what some say is the most polarized elections in american history. Plus slapping iran with with what they say are serious sanctions on the oil industry. Liec live in teheran with reaction. Some republicans fear he may have a negative impact on their states midterms. From cnn world head quarter atlanta. Welcome to viewers in the United States and around the world. Im george howell. And im natalie allen. Cnn newsroom starts right now. Thank you for joining us. U. S. President trump and former president barack obalm are on the trail. President trump conceded they could win a majority but wouldnt be to blame if that were to happen. He also pushed hiS Immigration message, telling crowds democrats want to invite migrants, crime and others into the country. I think it could be a red wave, i tell you what. I think it shouldby the democrats, and it could happening. Were doing really well in the senate but could happen and you know what you do, my whole life you know what i say . Dont worry about it. Ill just figure it out. On friday barack obama campaigned for Democratic Candidates in florida and georgia. He accuses President Trump and some republicans off lying and fear mongering. What we have not seen what were seeing right now is politicians just blatantly repeatedly, baldly, shamelessly lying. Just making stuff up. Thats what theyre doing right now all the time. Dont be bam boozaled, dont be hoodwinked. When words stop meaning anything, when truth doesnt matter, when people can just lie with abandoned, democracy cant work. Former u. S. President there. The current president fired back, accusing mr. Obama of broken promises during his presidency. More on this from Trump Campaign stop in indianapolis. Reporter President Trump continued his war of words at rally here in indianapolis. Trrs the president tore into obama who accused trump earlier in the day of telling lies. President went after obama said he told lies off his own and called attention to the middle name by writing out on a h with his finger. Its no surprise joe dawnally is holding a rally this weekend with barack h. Obama. Barack obama. I watched him speak today. He a very small crowd. They dont talk about that and they never talk about how big our crowds are. President also seized on the subject of immigration but took time out going obamacare. Democrats may want to seize on those comments as theyve accused the president of trying to weaken that law and its protections for people with preexisting conditions. Jim acosta, cnn, indianapolis. Thank you. Republicans are so deeply intrenched in some u. S. States its hard to get traction but this year a few of those states are genuine battle grounds. Democrat Stacey Abrams and republican ryan camp are locked in a heated debate for governor. Some big stars are trying to help these candidates win. Former president barack obama received rock stars welcome in atlanta. He came to campaign on behalf of Stacey Abrams. He headlines by saying this might be the most important election of his lifetime. The consequences of any of us staying home really are profound. Because americas at cross roads. The health care of millions of people are on the it it balance, making sure working families get a fair shake is on the ballot. But maybe most of all the character of our country is on the ballot. Obama spoke in familiar tones but he didnt mince words when he essentially called output and other republicans for the rhetoric that weve heard in the lead up to these Midterm Elections. Rhetoric he said is meant to divide us, make us angry and fearful. President obama the latest in a string off big names that have come into the state on behalf of each of the gubernatorial candidates in a dead lock race. The next one to come to town, President Trump on behalf of ryan chem. Lets talk more about this. Leslie is the head of the u. S. And Americas Program at chatham house, the Royal Institute of International Affairs live in london. A pleasure to have you on the show. Were seeing the former u. S. President barack obama hit the campaign trail in stark contrast of President Trump. Very opposite in messaging. Which message makes the biggest impact in what is clearly ea divided electerate . Remember right now as with many Midterm Elections is seeing widely as a referendum on the sitting president. Theyre trying to ignite the passion of their voters and to get them to turn out and vote because so much of it right now is about getting people to turn out and vote as opposed to necessarily altering the way in which theyre going to vote. They have very different messages. President trump, as weve seen, is really campaigning on a message thats about fear, antiimmigration. Interestingly in a context where the economy is very strong, rather than really making that his key message even when he talks about the economy, hes drilling down on the fear that there could be set backs if the democrats were to do well in these Midterm Elections. President obama saying lies and governance are just not american and what what we should be looking for. You mention the economy. Y but immigration, again mr. Trump pushing on that narrative of a caravan of men, women, children of babies coming to as he put it over run the country. Mr. Trump seemed to back away from his earlier suggestion that u. S. Military should shoot immigrants if they throw rocks. Listen on the before and after. Well talk about it. They want to throw rocks at our military, our military fights back. I told them consider it a rifle. When they throw rocks like they did at the Mexico Military and police, i say consider it a rifle. They do that with us, theyre go eing to be arrested. Theres going to be problems. I didnt say shoot. But they do that with us, theyre going to be arrested for a long time. Technically, lesley, he did not say shoot but is this that dog whistle thing . You Say Something and slap it down . Clearly its designed to rally the base and one interesting thing is whether hes pushing that immigration message in part because maybe his base hasnt seen the economic gains that america is more generally seeing. But hes clearly facing some constraints from the people around him. Deeply controversial, the idea he would send military troops and the idea that they would shoot. But those round him, that caravan is at least a month away. The timing looks deeply political and there are very serious people around him undoubtedly will be trying to walk him back from this strategy. One would hope. But he puts the words outthere, they have an impact. Theres a very significant backlash against that from people who think very seriously about the integrity off the u. S. Military. The economy doing pretty well though not the center piece when he is on the campaign trail. Thank you again for your time. Thank you.

As you know sanctions are starting on iran and you know iran is taking a very big hit. The iran sanctions that President Trump is talking about go into effect monday the same sanctions that had been lifted under the nuclear agreement. They order countries around the world to stop buying iranian oil and take action against port operators and ship builders. Mike pompeo says eight Oil Importers will get temporary exemptions. Pompeo has said the European Union will not be one off them. Our Senior International correspondent joins me from teheran, iran and youve been out talking with iranian about the sanctions. Reporter yeah, natalie and its a mixed bag of things that you hear from iranians. President trump come out and say these sapnctions are going to ht iran very hard. Theres no doubt thats the case. Ayatollah was on tv saying america will fail in its quest to dominate iranians. But regular folks on the streets very concerned about the Economic Situation in the iran thats already been developing with the economy in a free fall and more hardline elements here in iran continue to stay put. Reporter the usual chants against america more forceful than usual, during hardline friday prayers in teheran. Ripping into the u. S. We are encountering a real fight with our main enemy, america and theyre organizing a battle against us. As the u. S. Is set to hit iran with new crippling sanctions, defiance from religious conservatives. I think these kind of sanctions make us more powerful for the future. I think this is an opportunity. Reporter so far irans rulers not buckling under u. S. Pressure. If it was the Trump Administrations intention to weaken the iranian government, that doesnt seem to be happening. In fact many are uniting under military and in anger over washingtons policies. We are doing a big number on iran. Reporter sending irans economy and currency into a tail spin. Now the u. S. Will target irans Important Oil and gas sector, potentially a crushing blow to irans finances, causing concerns in this moderate area. The economy has started getting worse and worse this woman says. And every day items are three or four times more expensive than before and some even calling for talks with d. C. We need real negotiations that both governments would be committed to this woman said and they shouldnt be turned again. And deep concern as irans people brace for more economic hardship. So far the iranian government has said they dont want talk with the Trump Administration at this point in time and one of the things causing so much uncertainty is that people dont know how hard these sanctions are going to hit. They know its going to be pretty bad. How much oil some othese countries going to be able to import from iran. At this point in time anybody ps guess how hard it is going to be hit. Tr the oil and gas sector is such a major part othis can country ps economy and they have been able to expand after the nuclear agreement. Looks like a lot of that has gone away. Just exactly how mup they dont know. Two things stand out. Uncertainty and the lack of seeing a way forward as to how iran is going to be able to overcome sanctions and get on track to make them go away at some point. They go in place monday.
