If Trump won in 2020,

Who would be the Dem frontrunner for 2024?

[MATTROSE94]

Probably Pete Buttigeig, Phil Murphy, Andrew Cuomo, Gavin Newsom, Sherrod Brown, Gretchen Whitmer, or Stacy Abrams.

Stacey Abrams would've been a good contender.

I'm not convinced we'd even have a Presidential Election in 2024 (or at any point until Trump dies).

Assuming Republicans win/keep the House/Senate in 2022 (they'd have to rig the election, but it's doable), they'd probably figure out a way to declare Trump President for life.

Probably Warren, & I can't imagine who'd be able to successfully beat her. Bernie wouldn't run again, so she'd probably inherit a vast majority (i.e., >90%) of the progressive wing from him, in addition to many liberal-leaning moderates too, given the make-up of her voter base last year. Kamala would surely run again, but in addition to probably being tainted by the 2020 ticket's loss, she may not be as well-liked &/or seen as charismatic by as much of the party's base as Warren is. Yang would probably run again, & Governors like Newsom & Inslee would probably run too, as would Cuomo if the Democratic ticket's loss in 2020 somehow butterflied away his sexual harassment allegations, but who knows how popular they'd be? Not to mention, after a 2nd Trump term, the party will have likely moved even further to the left by 2024.

If Trump had won in 2020, the nomination, I believe, would have gone to a newcomer who hasn't been on the Presidential campaign trail yet.  The 2020 campaign really did damage to a lot of those that threw their hat in the ring, boxing them in on all sorts of issues that had questionable public support.

However, the two main issues of the general election (COVID and police funding) weren’t issues in the primaries.

[Agonized-Statism]

I'm gonna be bold here and say Ruben Gallego is the dark horse nominee. If Biden lost, his underperformance with Hispanics in the primaries and the general would be noted, and Gallego in a lot of ways fits the progressive-but-not-too-progressive Warrenesque mold that Democrats would be going for. Gallego, as a combat veteran, might also be a good fit for the tense foreign policy situation with a war probably already underway.

In any case, it would be some kind of unknown or "outsider". Two reality-defying Trump victories would seriously change the political landscape.
