A humiliating Super Tuesday night for Elizabeth Warren will finally put a stake in her presidential campaign — all thanks to her home state voters.

Warren suffered the ultimate slap from her constituents, a third-place showing in the Massachusetts primary, losing to a candidate who everyone counted out, Joe Biden. And it only got worse in the rest of the Super Tuesday states.

It’s over for Warren, and the only thing left is for her to make it official.

Warren’s campaign, which showed so much promise that she actually looked like the front runner last year, went down in flames with dismal showings in New Hampshire, South Carolina, and then on Super Tuesday, where she failed to even come close to winning a state. She even lost badly in her other home state, Oklahoma.

She should make a graceful exit, and go back to Massachusetts. Her once promising star power has been extinguished.

And here’s a Super Tuesday message for Bernie Sanders: Stop whining, Bernie. Your “the establishment is against me” shtick is getting old.

Here’s a novel way to beat back the establishment: Stop losing.

The socialist senator needed a big Super Tuesday string of victories to grab a firm hold of the Democratic nomination but Joe Biden’s early wins were depriving him of that.

Sanders lost badly to Biden Tuesday in the states of Alabama, Virginia and North Carolina, his second, third and fourth defeats coming on the heels of his South Carolina drubbing.

Biden shockingly won Minnesota and Massachusetts. And he even won in Texas, a state he wasn’t given a chance in.

Biden’s remarkable political comeback from the dead means it’s going to be a two-person race from now on, and it’s likely to get bloody in the days and weeks ahead.

Sanders was declared the winner in California, earning him a large chunk of the state’s 415 delegates, but he failed to put away Biden. In fact Biden is now the clear frontrunner.

Sanders’ big weakness — his failure to get black voters to join his “revolution” — proved fatal Tuesday night in states like Virginia and North Carolina, with large African American populations. It was the major reason Biden won big in South Carolina and a major reason Biden kept the momentum going on Super Tuesday. Biden won more than six in 10 black voters in Virginia, according to exit polling.

It was also a crushing night for former New York Mayor Mike Bloomberg, who dumped a half-billion dollars of his own fortune into Super Tuesday states.

Leading up to the primaries in 14 states on Tuesday, Sanders complained that Democrats were trying to rig the election against him, this time resorting to the dreaded third person — a sure sign of inflated ego. The Sanders campaign continued its whining on Tuesday.

“The political establishment has made their choice: Anybody but Bernie Sanders,” campaign manager Faiz Shakir wrote in a fundraising email. “The truth is, we’ve always known we were taking on the entire damn 1 percent of this country. But we have something they do not have: people. Lots and lots of people.”
