I mean the question is “what would you do if he stepped aside” and he answered that, and then pivoted to “but I don’t want him to.” Maybe entertaining the hypothetical is something, but I don’t know, feels like everyone is reaching a bit here, to me.
He had the option of resisting the hypothetical though. "That's not going to happen, I'm not even going to get into that, what a ridiculous question"
Interpreted as politician-speak.... I dunno. Seems pretty far toward the "open to Biden dropping out" end
I guess since the question specified “if he decides that, and he has to decide that,” which colors how I read the response. They’re both flavors of “I support the decision he decides to make” as I’m reading it.
