Policies vs. personalities?
Trump has a better policies AND a better personality.
This idea that President Trump is obnoxious is a fiction - an invention of the fake news media. In reality, he is quite charming.
True, many people have bought into this myth that he is obnoxious and rubs people the wrong way - but these are not people who would ever consider voting Republican. The only people who believe he is obnoxious are people whose only exposure to Trump is a daily dose of MSNBC/CNN fake news - selective sound bites heavily edited and taken out of context - designed to make him look bad. In other words, these are committed Democrat voters.
These are not people who voted for Reagan because he was polished but will vote against Trump because he is crude. No such person exists on the face of the earth.
They have never actually listened to a Trump rally speech in its entirety and they never will. Trump was never ever going to get these votes - so the fact that they believe he is obnoxious or a Hitler is entirely inconsequential.
