To vote, donald trump had the same percentage of the vote as he does among the probable to vote. The fact is this particular poll theres never been an error in the poll large enough going back to the first Des Moines register poll, any error even close to large enough to indicate donald trump is heading close to anything other than a massive win. And i know from covering these campaigns the Des Moines register poll is basically the cold standard when it comes to these polls right before the iowa caucuses. How predictive is it historically . Lets look at this historically. Best iowa showings, george w. Bush in 2000 help us out here. These are the final results. George w. Bush with 41 in 2000, donald trump obviously at 48 ahead of that. Ill also note in the final Des Moines register poll we were talking about, he was at 43 which was the best showing ever in that preelection poll
