Sanders actually has many of the trappings of a unity candidate--he’s well known, he’s well liked by the rank-and-file, and his unwavering message has become a staple of party rhetoric even in the boardroom wing of the party. Most important of all, he actually has a message. Of everyone else in the race, only Warren has offered an actual reason for running. The two make similar cases: The U.S. economy and the U.S. political system are stacked against working people. It’s a good message, because it’s true.

Everyone else in the field, meanwhile, is offering an increasingly unpersuasive version of “I alone can beat Trump!” These candidates have little to say, because they aren’t targeting voters, they’re auditioning for donors. The real message isn’t “I can win,” it’s “I’ll make sure you’re still in charge.”

If you ask me it's the other candidates who need to get ahead of what Sanders has done to them.
