Biden allies have already started grumbling about Bloomberg

Sometimes the grumbling was veiled by humor.

“Wasn’t Rudy Guiliani mayor of New York? And he didn’t run for president?” Terry Shumaker, a top Biden endorser who co-chaired former President Bill Clinton’s New Hampshire campaign, quipped. “How did that work out?”

Other times it was more overt.

“Testosterone is a very poisonous drug,” Democratic strategist Celinda Lake, who is working with Biden’s campaign on polling, said bluntly. “Democratic primaries are 59 percent female and this kind of candidacy is not the way to their hearts.”
