There is in the realm of 230 million eligible voters in the United States. One quarter of them have not registered to vote. Another quarter are Republicans. Something like 55 million. 65% of those are dedicated Trump supporters, for whom he can do no wrong. 35,750,000 people. That's his base. He got 63 million votes last go around. That leaves about 27 million Trump 2016 voters who are not fanatics. How many of those voters are likely to vote for him again? Probably the other 20 million Republicans who did so last time. My guess is about a third of the remaining 8 million voters. Let's just say 3 million. My prediction is he gets about 58 million votes this go around, assuming he survives impeachment (which I strongly suspect). If the Democratic nominee gets in the realm of 63 million votes (Clinton got nearly 66), they will win all the toss-ups. If, however, voting turnout is higher than the 57% of 2016, they could eclipse 70 million votes. That would tip many of the Senate races, too.

My head says 68 million to 60 million, D/R votes. My heart is still scared.
