The perfect example is Georgia, a state the Republicans dominate except for the US Senate, Trump thru his comments and actions managed to alienate enough Republicans to allow 3 straight Senate elections to be won by Democrats
raffensperger and kemp colluded and co-operated with the left to rig the election so Trump lost, in exchange for the left gaining senate seats.
Georgia has some of the most corrupt politics vs the other states.
Even if all your allegations are true, Georgia still has two Democratic senators and Trump dumping all over them had a lot to do with it.
