I think they are, yes. But I'm not in the DNC Hive mind.
I will say there's a big difference between not picking a minority like they did in 2020, and pushing an already picked minority aside, like they would need to do now.
Now they don't even have the cover of Primary Elections to pretend like the voters are the ones who really want the white guy. I think if they dump her now, they will have a really difficult time getting the younger, activist base interested in whomever the replacement is.
I guess we'll see in Chicago what they do.
