Perhaps the only bright spot for Rs this cycle:
Texas and Florida have shrunk Ds national map. Ds had a very large majority of their "mainstream*" incumbents and challengers run this cycle and they won nearly every race against "toss up" bat shït crazy Rs. NC, thankfully, tilted back to rationality and went mostly R, but it is something to watch. Expect Ds to try to turn NC via Raleigh and Charlotte (areas now hated by rest of NC) much like Philly dominates Pennsylvania.
If Rs had run reasonable people, they probably take 20 more seats, maybe 30 away from Ds last night.
So Rs have to ask themselves this:
Do they want to focus on yet unproven election tampering (FOCUS ON BALLOT HARVESTING damnit!) or do they actually want to win races? Hard to set agendas when you are in the minority.
Also, Arizona is far more damaged for Rs than they thought. It will take an immediate and long term "Florida way" plan to turn the tide in the desert say 8-12 years from now. Rs in Phoenix have utterly failed in putting into place reasonable voter ID measures and it gas cost them amd will continue to do so. The "Florida Hispanics to Red" technique might also prove fruitful in Nevada (an emerging bellweather state).
Lastly, I believe last night's results shoved the nation much closer to either a bitterly negotiated or violent breaking up of the US.
