At this point I wonder whether this TL or the Reagente TL is more likely to become a reality. I do not think either will become a reality starting in 2020 though, since Biden is a bad fit for Cordray and since well, Trump won and not Clinton.
Reagente's does have a decent chance at happening if Biden wins and the GOP wins the Senate though, turning President Biden into a 4 year lame duck that loses reelection to Carlson in 2024 or something.
For this one to happen, Sanders or Warren should have been the Dem nominee.
(yes I know neither will actually happen but it's still fun to speculate whether the future will be on the darkest timeline or the dankest timeline)
Knowing this mortal coil, probably the darkest timeline.
