Back in 94 you had a few Dems change parties. If Trump restores integrity to the vote, to block all non-citizens, I would presume we’d see another wave of transfers.
If California is stupid enough to exit the union, there will not be another Democrat majority in either House, nor President for a generation.
Do it!
Back in 1994-96, you still had Conservative-voting Democrats in Congress, however tiny. There’s no right-of-center Democrats left.
