Tops on that list is "OMG Joe Biden Wanted Elizabeth Warren to Be His Hypothetical Running Mate" by Ben Mathis-Lilley at Slate. It begins:
You guys! I have been telling friends, colleagues, Chipotle cashiers, and random people on the street for months that Joe Biden and Elizabeth Warren would make a great "unity ticket" in the event that the Democratic primary ended up in a stalemate between Hillary Clinton and Bernie Sanders. Biden is a well-liked "establishment" Democrat with foreign policy experience, Warren is a tough-talking progressive who'd appeal to the left wing but isn't so radical that she'd alienate moderates ... it just works. Hillary is going to win, of course, so this is all moot, but who cares, because it turns out that JOE BIDEN AGREES WITH ME....The link goes to the Politico story — which I'm characterizing as a feeler — "Biden wanted Warren as his VP/The Massachusetts senator was 'noncommittal,' but warned of a backlash against his pro-Wall Street votes in Senate."
That is a feeler, isn't it? I'm assuming that was put out there to see how much excitement it would generate, how many influential people would jump and start promoting that escape from what could be portrayed as the sinking ship that is Hillary. The FBI investigation is out there, in position to have a major or meager effect. You guys!
