Which Republicans do you think will run from Trump? Elected Republicans? Republican voters? Both? I think that is wishful thinking. They won't be running right away that's for sure. The Republican party is in a terrible place right now. Trump has destroyed the party...completely. He has embraced white nationalists, QAnon loons, and every nut and scumbag that he can. Why? Because he is aware he needs every one of those votes to pull off the slimmest margin of victory. He knows he can't afford to lose that "base" because the margins are tiny. This is why he looks so likely doomed to lose because he is bleeding Republican voters...I've never seen an effort like the one being made by Republicans this time out to sink a Republican president. I think it is working. 

The only totally brainwashed voting blocks Trump has are white nationalists, QAnon crazies, and evangelical Christians. Now the sad thing is...all of these people are totally reliable when it comes to showing up at the polls. They also now do not give a flying shit about the Republican party...they are the Trump party. They won't be running from Trump and they will threaten Republicans and they will primary Republicans with their own lunatic candidates. This will likely go on for years. What Trump has unleashed is going to be really tough to get back into the bottle.
