Four elections with a Democrat landslide and a divided opposition?
It seems like in your write up the Democrats will end up being like the LDP of Japan, while the Republicans become like the divided Democratic Party of Japan, frequently suffering losses and winning once in a blue moon.
Great update. The Trump-Pence era fractured the GOP forever. The TL extends beyond 2030 as stated in the title.
All this is is the initial Democratic hold on the Presidency lasting an extra 4 years, it just means the Cordray alignment is going to be stronger than the Reagan Alignment, not that the GOP is completely crippled.
