So personality over policy? Says way more about those who voted this way than the candidate.
My son actually just did this topic in his first debate scrimmage. They lost (got trounced by sophomores who had been doing it longer). It's the issue of whether character matters in politics. For some, Trump was just too much (ranging from vulgar to mean) despite the policy of the other side. It's not just a Trump thing....it came up the other way with Bill Clinton and Biden (though no one so far has come forward with definitive evidence he's involved in his son's shady business dealings)
