Never seen before. The polls are open for two more hours in wisconsin, the only primary on this tuesday, but its a big one. Ted cruz and Bernie Sanders are leading in the polls, and the winds could provide them with more momentum in the race for president. From milwaukee with the very latest, mike, there are 42 republican delegates up for grabs tonight. And how crucial is this for ted cruz . We dont know where ted cruz will be in milwaukee, good evening, richelle, its important for ted cruz because what hes trying to do in the only states up for grabs is trying to put himself further on the map. And trying to dismantle donald trump in a place where he came for vindication and said to ted cruz, you should not have won in iowa and i will win in wisconsin, very similar in the makeup of their voters as iowa, and then you look at tonight, some of the exit polls, and all of candidates talking about the exit polls, and they look good for them. But if you look at the rust belt tonight. If you see ted cruz doing well in the rust belt where there are not many evangelcalls, it could signal a change. Donald trump has been doing something untrumpian, i dont know if thats a word, but spending a lot of time on the ground in wisconsin, and thats something that the opponents usually do. Whats the strategy here . Yes, hes being decidedly, as you just coined, untrumpian, richelle, and he has been taken to big stages in this campaign, staying out of the airwaves, and phoning in shows, but you start to see him in diners, and doing old time retail politics, which is not how he got himself in the game. Yesterday in once which is, he showed optimism because he knows that he has to win this it state to stop a terrible time. And heres donald trump in milwaukee yesterday. I think that its going to be a great day in wisconsin, and i think that were going to to do very well. I dont know, but based on the enthusiasm, how do you think were going to do in wisconsin . I think that well do very well, i hope so. Thats what donald trump is saying. Privately the campaign tells us that while its not looking good here, they are looking to states where they think that they will be on lit rate ted cruz on the 19th, in april, in connecticut, rhode island, maryland. Those are places where he thinks that he can do better, but theyre looking out in those states for john kasich. Bernie sanders, and Hillary Clinton, the polls show that Bernie Sanders has a slight edge, a win in wisconsin, what would that do for his viability as a candidate . Well, listen, Bernie Sanders has been talking about his viability and his electability that he can still win this. He cant continue that conversation if he loses, and yes, the polls have shown him gaining on Hillary Clinton and passing her, and the clinton people are privately sending out emails, saying that the numbers dont look good here. So what this does, if Bernie Sanders wins, thats another one, thats six out of the seven for Bernie Sanders. And he does know where this Campaign Goes from here though. If he becomes more difficult, and if he makes a big play in Hillary Clintons adoptive state of new york, and in his old state of new york. He will continue the conversation about his viability and nominate ability and that starts tonight in wisconsin. Feeling the bern, thank you, mike. And look at just how much is at stake tonight. Lets bring in david schuster. Richelle carey, feeling the bern, and this is a numbers game for everybody. Lets start on the democratic side. 86 on the democratic side. And its proportional. Lets suppose that Bernie Sanders wins 5545, and he would get 40 in terms of the delegates, so the idea for Bernie Sanders is to try to get a net gain in terms of the delegates, and Hillary Clinton will pick up some, even if Bernie Sanders wins. The key for the sanders campaign, in terms of the overall pledged delegates count, and the theory is that if he overtakes her before the pledged delegates, all of those super delegates would switch sides and put him over the tom. In order to close this 263 pledged delegate deficit, Bernie Sanders needs to win the rest of the delegates by an average of 5743, including wisconsin tonight. If he gets a big victory in wisconsin, it helps, and it keeps alive his dream in new york and pennsylvania and california, in order to overtake Hillary Clinton going into the convention. On the we know side, wisconsin is a winner take all hybrid. Whoever wins the wisconsin primary even by 1 vote gets 18 of the delegates, and there are 24 that remain. Those are commit bid the eight congressional districts, and the winner in each of the congressional districts gets three. There are two where donald trump is going to to do pretty well. Lets suppose that ted cruz wins, and donald trump is hoping to pick up some of the delegates at play tonight. But as Michael Shure points out, if cruz can win wisconsin donald trump, 736, and he needs 1,237 to win. Theres no way that ted cruz can close that gap. But cruz, with caseics help, and perhaps rubio at the convention, what they can do is perhaps keep donald trump, with a couple of victories to come, they can keep donald trump from getting to the 1237 he needs to lock in the convention, and the delegates who need it going into the convention, and thats where you hear them talking about seconder and third ballots, where they admit be able to deny trump the nomination. The catch here, richelle, there was an exit poll today where 60 of delegates in wisconsin said that they want whoever has the most votes, even if theyre short, they believe that that person should get the nomination at the convention. 42 believe no, we plenty the delegates on multiple ballots decide. So you have them thinking that we need this brokers convention. Ted cruz tonight. Every single election, and were going to talk more about that. Always unpredictable. President obama is being pressured by the Treasury Department so crackdown a conversion, Large Companies purchasing Smaller Companies at a lower tax rate. Mike viqueira reports. Reporter good evening, richelle. Its a controversial issue, a practice thats raising eyebrows ream particularly with a highprofile case, the american pharmaceutical giant, pfizer, and the purpose, to avoid as much as 40 billion in u.

They cracked down on tax conversions, putting forth new rules to stop the pfizer conversion, and president obama appeared in the White House Briefing room to back that up.

The scandal, 1 million documents, exposed by investigations by an International Consortium of journalists, showing that many of the rich and powerful around the world are hiding their money, and president obama said that its not illegal whats the scandal. But its whats legal. And it should be illegal to try to move money around, engage in transactions, simply for the purpose of avoiding taxes. Richelle. Mike viqueira in washington there.

Reporter it is as far as you can imagine from iceland to the virgin islands, but his wealth caught up to him. An ice stream parlor, named after the Shell Company that he and his wife established. Its very sour, and leaves a sour taste in the mouth. Yeah, a bitter taste. Thats how you feel about it. Im sad and ashamed to be an icelander. They confronted him about the tax dodge, and he spent monday saying that he wouldnt resign and tuesday saying that he would if the Coalition Partners wouldnt stand by him. Its a standoff, but many think that he wont last for the no confidence vote on thursday. There are no meetings with charlment or Chamber Meetings or anything, because people kneel that the parliament continue function in this state of kries, so we have a fullfledged crisis that needs to be solved. And everybody except the Prime Minister himself recognizes that this is doing tremendous damage to the International Reputation and contacts. Its a betrayal of the people. They recovered from the bank crash, and Construction Projects have restarted as the country has picked up. The banks are weak, and the capital controls make a limit on how much icelanders can even take out of cash machines. The idea that the Prime Minister has been helping his wife to hide tens of millions of dollars so far away is for many people absolutely infuriating. So part of the language of protests here.

The refugee crisis, on friday, the first group of two Asylum Seekers was sent yesterday. Greeces Migration Office stels that migrations have been suspended. The numbers are not sufficient as to send the people back to turkey. The majority of people who are locked up in Detention Centers, there are approximately 3,000 of them on greps islands, want to apply for asylum.

But people in the Detention Centers are increasingly anxious, worried about their future. But this is going to take some time. The greek Officials Say that the normal process takes three months, for the right of appeal. But theyre promising to speed up the process and the 3,000 locked up in the Detention Centers, theyre not among the 50,000 who are stranded in grebes. Those people are not part of the eu turkey deal. Reporting from the island of lesbos. A motion to impeach south africas president has been repeated. Trying to keep him safe. And how potential voters are viewing the president. Reporter it started as fireworks and an attack on the freedom fighters. Fighters and a call for the speaker of the house to step down because of a possible conflict of interest, but she refused, and it began with a democratic alliance. Because the Constitutional Court judgment removes any doubt that the president has forsaken his oath of office. Reporter the Economic Freedom fighters screw more blood. Even after that constitutional accord, no single individual has been held accountable. And you want us to believe that you are protecting the constitution. You live by the rule of law. We are all equal before the law. Reporter the governing African National congress is the majority and the motion to impeach was easily defeated by 243 to 143. But the office has been invigorated.

The public will have their say at the local elections, and many people are frustrated. I like him, but the way that they treat them. Anc is not for him. The ancs base is vast and deeply rooted in its liberation history, which cannot be liberated. Some voters may be unhappy with the president , but they will still vote for the anc, because they feel that its the only party that truly represents them. If they punish them in the elections, it could use them as a mandate to recall them. But there are a lot of variables in the equation, and the president has proven time and time again that he is a survivor. Today china announced new restrictions on trade with north korea.

How the city of new orleans wants to rebuild their trade partnership with cuba and a British University criticized for bringing in more out of state students. Why administrators said they had to do it. Californias financially troubled University System is accused of bringing out of state students in the california zone. Out of state and International Students have to pay a higher division. Entrance standards with better rates. A state audit found that out of state applicants had an easier time getting into university of california schools than instate students. In other words, they had a lower bar to enter. Its very disturbing and disappointing that the school would do that. When your motto is to serve california residents and offer education. The reason for this, out of state students pay more division, and for a Uc School System with tough budget cuts, they have been an important revenue stream. There has been a disinvestment. The amount of money that they receive per student has declined pretty dramatically overtime. And what they have done is increase tuition in face of loss of revenue. They receive 250,000 a year in fees compare to local students, and the university has started accepting more of them. Since 2008, the number of nonresident graduates has stripped from 5 to 15. 5 today. Beyond want numbers, thats playing out on campuses in real ways, creating what students say is a divide between the haves and the have nots. What the problem is now, theres a growing inequality, or a certain type of student coming in as an instate student, and those coming in as an out of state international student. Muddying the waters, just this monday, the university of california announced an increase of 15 in the number of california students it has offered admissions to in the next academic year, and the university has fought back, denying the state audits finds, staying that the u. S. Report went on to point out that californias are still at a higher rate. And all applicants are somewhere in the uc system. And the percentage of out of state, including oregon, iowa and michigan. All of these numbers and statistics making it tough to assess whether instate students are really at a disadvantage. Aljazeera, san francisco. Congressmen from louisiana are headed to cuba tomorrow.
