My guess:
Democrats will take the Senate and may retain control of the House.
The fix is in.
I think the Maga candidates are ready for the cheating. If they have a good plan and stick to it, we have a chance. It’s not going to be easy but throwing in the towel now makes it easy for them.
If the Dems do get away with stealing the election, I think that every single Repub should simply walk out and quit; then the Dems can own the disaster.
