This is just what partisanship looks like. The individual doesn’t matter, you boost whoever the party chooses because the party says so. Sometimes it’s embarrassing, like when you have to defend Joe Biden’s dementia one day and then immediately switch to being excited about his replacement the moment he drops out, but that’s the game. They know she was an unpopular and unlikeable candidate with poor judgement and worse leadership in the 2020 primary, and they’d probably have preferred Biden had stepped aside a year ago so the party could have had a real primary. That doesn’t mean they’re going to express any shame or doubt, now or ever.

For a lot of people, electoral politics is very literally a spectator sport.
