In May, when the Register last polled, 27 percent of likely Iowa GOP caucus-goers viewed Trump favorably while 63 percent regarded him unfavorably. In the new poll, which was released Saturday night, Trump's favorable number is at 61 percent and his unfavorable at 35 percent. As The Washington Post's Chris Cillizza exclaims, "In the almost 20 years I have spent following politics closer than close, I've never seen anything like the total reversal in how Trump is perceived by Republican voters. It is, quite literally, unprecedented." The Trump candidacy has rewritten - or at least smudged - lots of the rules of conventional politics. He says things that would derail other peoples' candidacies. His shyness about specifics on, well, anything would be seen as a lightness bordering on cluelessness in other candidates. His pick-a-fight-a-day mentality would be seen as overly aggressive and tonally off if anyone else in the field did it. But, of all the amazing things that Trump is doing - whether he realizes what it is he is actually doing - his ability to totally turn around his image is the most remarkable. It's not something we've seen before. * * * It's different this time...
