Yep, just like Trump was a dream come true for the Democrats... wait.
I do think Warren would have some issues as the Democratic candidate, but she'd be far from the worst candidate Democrats could put up.
Yeah, that would probably be Booker, Cuomo, or McAuliffe, out of the plausible contenders. One thing Warren does have going for her is that I don't see the kind of intra-party strife that manifested itself during the last cycle happening again under her watch; she can reasonably appeal to both the Sanders and the Clinton wings. But someone like Booker as the nominee would intensely exacerbate the divisions within the Party.
