Bloomberg will only get my vote if he’s the nominee, but I really suspect he will pick Abrams to be his running mate, because he’s smart, knows what his weaknesses are, and has worked with her. And I think she’d accept.
I don’t know what pool of candidates Bernie will pick from. There’s a non-zero, though I think small, chance he could pick Tulsi. But he could also end up picking Pete, thinking it’s a radical choice, when it really isn’t. He’s the only existing candidate who could possibly think Gabbard is a reasonable choice.
