Idk, my read is that this is a "hi, people are largely floating a white candidate to replace Biden, that isn't happening" statement. And since I highly doubt most people calling for a switch will seriously consider Harris for totally not at all obvious reasons, this is not leaning towards a switch
Yeah, I just think the valence is just the opposite of how people are taking it. It's acknowledging a serious issue, and putting a powerful constituency firmly in the incumbents camp. This is notable. I just think that because of who that constituency is, it's generally seen as either /1
A spoiler or subordinate. Ex: how in 2020 that constituency "threw" "stole" the primary to Biden. They aren't people to be courted or counted. The headline here is that Biden/Harris just got the institutional endorsement of the most powerful pole in the Democratic tent.
