That's a dangerous assumption in an election year where even if they do not vote R, they may not vote at all (this is a position voiced by many, and prevalent in pop culture) which could hand the election to "America's Hitler".
This year, criticism should be levied against both parties, and that's not happening. Republicans in congress literally just applauded the genocide.
Next year, assuming Harris wins, continue to protest their position.
This is just sad. It's like a victim of dv who quickly corrects themselves when they say something their abuser doesn't like.
