I’d recommend you actually read the very article and explicitly try and look for a genuine quote where an individual explicitly is quoted as saying Biden should drop out.
No, you’re desperately trying to ignore why they are trying to be delicate; these are people who are close to Biden, and they understand that they need to try to persuade him to step down but also if he chooses not to they need to be able to try and drag his corpse over the line.
If Biden had their full support they wouldn’t be qualifying all their endorsements, they wouldn’t be phrasing it as “Whoever the candidate is I’ll support them.” They would be saying the discussion of his age is nonsense, but they’re not because they understand this is one thing they can’t just pretend isn’t a reality. They’re positioning themselves for both scenarios because there are closed door meetings about this topic.
And besides, other dems have been more explicit, including Adam Smith and Pat Ryan, both of whom did not soften the blow at all:
These are not fringey left dems, they’re right-wing, party establishment.
But yeah, I can see you’re not ever going to be honest about this, no matter how much evidence you’re shown. You’ve got some other agenda here besides a democratic win, and I don’t really care to know what it is honestly. Good bye.
