In Seattle, Booker joked that the campaign had instructed him not to “stick  your foot in your mouth again . . .So this is my probation speech.”

Booker’s comments on “Meet the Press” opened the floodgates for other  Democrats to get off message.

In recent weeks, Massachusetts Gov. Deval Patrick said, “I think Bain is a  perfectly fine company. They’ve got a role in the private economy and I’ve got a  lot of friends there.”

Then former President Bill Clinton said Romney “had a sterling business  career,” and endorsed an immediate extension of the Bush tax cuts.

And yesterday, former Pennsylvania Gov. Ed Rendell — who used to head the  Democratic National Committee — minimized Obama’s background entering the  presidency, saying Hillary Rodham Clinton “would’ve come in with a lot more  executive experience . . . I think the president was hurt by being a legislator  only.”

For his part, Bill Clinton personally apologized yesterday for going rogue on  Obama.

“I’m very sorry about what happened,” the former president told CNN. “I  thought something had to be done on the “fiscal cliff’ before the election.  Apparently nothing has to be done until the first of the year.”
