Iowa Republicans do not care about the criminal charges against Trump
I wrote earlier that pre-caucus polling showed that Iowa Republicans didn't care about Trump's legal problems. ABC's Iowa entrance polls support that. Sixty-three percent of caucusgoers said Trump would be fit for office even if he were convicted. Seventy-one percent of that group voted for him. So to Julia's earlier question, I think part of the issue, as she noted, is that while there are some anti-Trump Republicans who want an alternative, a majority of Republicans left in the party don't think Trump did anything wrong, or that even if he did, he's not disqualified from future office.
