What makes you think the Dems won't have total control after 2022?
The Dems have perfected cheating in this election. They'll allow just enough Republicans to win to have a "loyal opposition" but the Dems will be in control of everything.
The solution is to vote every Republican out. Crash the system. Create chaos. Make the powers that be realize the joke is over.
The corollary would be that it might require more than an election.
