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.
Tbf, the median House seat is further left than WI and it's not like the GOP has nominated a particularly great slate of candidates either beyond a few incumbents and the few places where the GOP electorate hasn't gone full Trumpism. It's just we don't hear about it as much as House races tend to be much more of a local thing whereas Senate races are nationalized.
