President Harris or President DeSantis makes a big difference here. One interesting thing I've always wondered is if this will be Collins last term - and I think it will be since she got a big scare even if she won decently. That should be a good pickup opportunity for Democrats but the state may trend right by then. Pickups opportunities for Democrats...
GA (if Perdue wins the runoff)
ME
NC
TX
Pickup opportunities for Republicans...
MI
MN
NH
We're getting to a point with these Senate classes where the polarization if making for very few competitive races. 2024 is the only one where Democrats still have a lot of seats in red/redish states.
Dems really just have three red seats left in the 2024 cycle (and in the Senate as a whole): WV, MT, and OH.
