1. Dems need at least 52 Senate seats to get 50 votes (Forget Manchin, Tester & whomever flips a red state).
2. The more court-packing talk, the harder it is to win those seats.
3. If you don't campaign on it, it's illegitimate.
Cool it with court packing.
Campaign on expanding the Court to 15 seats, even if you think you have a brilliant mechanism for making it fair.
How about winning an election or two before trying to overhaul the courts?
At least FDR did that.
Sure, there were other factors, but this election doesn't bode well for this pacing strategy.
FDR won in 1936 on mainstream pocket book issues, not court reform.
But after FDR proposed court-packing, the Dems were throttled in the 1938 midterms (I'm oversimplifying a bit).
