After Super Tuesday comes "What Happened" Wednesday. Today, Rolling Stone reporters from both coasts debrief what we know about how the biggest primary day went, and what's next. Senior writer Jamil Smith and politics staff writer Tessa Stuart talk about Bloomberg's role, Warren's path or lack thereof to the nomination, Klobuchar's endorsement power, and of course, what Bernie and Biden need to do in the late-March states to wind up on top once the Convention rolls around.
