The biggest loser, the polls found, is Donald Trump, who has surged to the front of a crowded Republican primary field nationally but is viewed unfavorably, by almost a 2-to-1 margin, by voters in those states.

In Colorado, only 34% of voters said they see Clinton as honest and trustworthy while 62% said they don't. In Iowa, the numbers were 33% to 59% -- a drop from 45% to 47% in April. And in Virginia, Clinton did best, at 39% saying they trust her to 55% saying they don't.
