Just when you think the Democrat primary cannot get any more acrimonious, it does. Bernie Sanders has been ratcheting up the rhetoric against DNC chair Debbie Wasserman Schultz, claiming that the DNC primary system is rigged and that the concept of superdelegates is inherently unfair.

He’s right, of course, but that’s not why he’s losing; he’s losing because Hillary is kicking his butt at the ballot box. However, that isn’t stopping Bernie from mounting a virtually relentless campaign against DWS personally. He’s now stepped it up another notch, endorsing DWS’s primary opponent Tim Canova, and promising that if he’s elected President, DWS will be fired.

Vermont Sen. Bernie Sanders on Saturday said he supports Democratic National Committee Chairwoman Debbie Wasserman Schultz’s Democratic opponent in her August 30 primary, adding that if he is elected president, he would effectively terminate her chairmanship of the DNC.

Sanders, whose campaign has engaged in an increasingly bitter feud with the DNC chairwoman during his presidential bid, said in an interview set to air on CNN’s “State of the Union” that he favors Tim Canova in Florida’s 23rd congressional district. Canova is supporting Sanders.

“Well, clearly, I favor her opponent,” Sanders told Tapper. “His views are much closer to mine than as to Wasserman Shultz’s.”

Sanders added that if he’s elected president, he wouldn’t reappoint Wasserman Schultz to head the DNC.

In a response to Sanders on Saturday afternoon, Wasserman Schultz insisted she would remain neutral in the Democratic presidential race despite the Vermont senator’s endorsement of her primary opponent.

“I am so proud to serve the people of Florida’s 23rd district and I am confident that they know that I am an effective fighter and advocate on their behalf in Congress,” Wasserman Schultz said. “Even though Senator Sanders has endorsed my opponent, I remain, as I have been from the beginning, neutral in the presidential Democratic primary. I look forward to working together with him for Democratic victories in the fall.”
