Heilemann was on Hacks On Tap yesterday & was saying that he's heard from Bidenworld that Joe keeps coming back to Warren as somebody he likes ("simpatico") & who meets the threshold of being both immediately & obviously qualified for the Presidency on Day 1, & that many in the Biden orbit perceive Kamala to be self-serving (in contrast to, say, Obamaworld never having perceived Biden as looking out for Biden rather than Obama).
This whole thing is just... lmao
Warren is just a disaster in waiting. This may be anecdotal, but there are a number of people that I've talked to who are on the fence about Biden and view her as a deal breaker. He risks losing support with independents with her.
Demings, Duckworth, and Harris are safe choices.
This almost sounds like folks looking for an excuse not to back Biden or... who assume he'll croak soon and thus want their favorite moderate who's younger instead. Both are a bit on the selfish side as one case is a disingenuous priming expectations for those who were going to be on team Trump the whole time but wanted to pretend they weren't horrible human begins and the other is bound entirely in fear of specifics of policy while ignoring the existential threat the GOP and this president pose to the nation. Note I would say similar things about the Bernie or bust folks who might accept Warren, maybe, but no one else.
In other words... one might want to try to sway one of these two groups, but... Biden's probably better off ignoring the wants of the ultimately selfish who even if he bends over backwards for them in the hope of meeting their demands are far from interested in supporting him, and instead Biden should be opting for the person who would make the best president if they happen to need to be. And that is a much more complicated calculation.
