Super Tuesday
The establisment strikes back. Joe Biden takes the lead in the delegate count on Super Tuesday. Most notable is that Warren should have endorsed Bernie, like Pete and Amy did for Joe, but she didn't, which shows her allegiance is to the party and not the movement.
A lot of democrats would vote for Trump over Bernie because Bernie represents a threat to their market-based prosperity. A lot more people, though, are not invested, or they prefer to afford a more civilized approach to society than what we currently have. They support Bernie, who nails it tonight, talking to a crowd in his home state.
