I don't remember it that way at all. The South was solid all the way.
No, the GOP Senators in NC, FL and GA all won by much much larger margins then Trump. A lot of solid Red districts came in very weak for Trump. The pollsters look at that and said “a lot of GOP people don’t like Trump” and that was the case in 2016. A lot of church going GOP voters did not like Trump. They thought he was a NY Liberal pretending to be “Conservative” who would disappoint if elected.
I think the last 2 years laid those fears for Trump to rest. The Polling Groups took it to represent a change in voting patterns.
Tonight we will see who is right.
