Policy Is King In 2020
Make no mistake, the upcoming election will be about policy. Except for the absolutely fractal part of the population voting for Jo Jorgenson, most will vote for policy.
Republicans won't care if Trump is a racist, they already believe he's not (no I won't bias this one way or another with my opinion). They're going to vote for him because he's actually accomplishing the conservative agenda.
Democrats won't care if Biden is senile or a pedophile, they already believe he's not (no I won't bias this one way or another with my opinion). They're going to vote for him because they believe that he'll actually accomplish the liberal/socialist agenda.
You can demagogue people into boxes if you want for who they do or don't support, but in the end, people vote for policy not people. People haven't voted for people since Carter or Reagan, and MAYBE the first Bush.
Policy, policy, and policy are king, and whomever the people think can accomplish their favored policy is who those people will vote for. It's not about racism, pedophilia, senility, or the myriad of other things that people want to attempt to throw out into the arena.
The more power the office of President holds, the more policy becomes king in the election cycle, and nothing else seems to matter. Don't like it? Maybe it's time to reevaluate how much power the President has.
