Right now, I’m predicting a 52-48 D senate and a 228-207 R house. Anything could happen though.
I really think if Democrats win this seat they'll narrowly squeak by in the house. Unless Johnson is just that bad an incumbent.
Unfortunately, I don't see the two as connected at all. WI is a dem leaning state and RoJo is a far right wing trumper who tried to push fake electors in WI and MI. If he loses I think it's b/c of that and not b/c the environment has gotten so competitive for dems that they hold onto the House.
