frankly i think when you look at the presidential candidates, they have all pretty well made their position clear. this has become the biggest political football i've seen in my political career, this issue of immigration and what to do about it. >> here is the thing to understand about donald trump. he seems to be popular, leads in a poll, leads it. he's been near the top of other polls. in this incredibly diffuse field it doesn't do much to do well at the campaign. he's historically unpopular candidate. polls show a whopping 57% of republicans have an unfavorable view of trump. the numbers among all voters are worse. one may poll showed net favorability rating among all voters minus 55, far worse than any other candidate. a february poll showed vladimir putin his favorability rating minus 58 just three points worse
