Update 3:25 p.m. Bachmann called into Radio Iowa to address the story herself. Politico has her statement: 

“That is a shocking story to me,” Bachmann said. “I don’t know where that came from. We have called staff in New Hampshire to find out where that came from and the staff have said that isn’t true, so I don’t know if this is just a bad story that’s being fed by a different candidate or campaign. I have no idea where this came from, but we’ve made calls and it’s certainly not true.”

Update 3:15 p.m.: Michele Bachmann's campaign says it hasn't heard of anyone in New Hampshire quitting, Fox News reports. Fox News's Carl Cameron writes that the campaign says, "until the Bachmann campaign hears from those individuals who have reportedly quit, the campaign will not comment further" but Cameron also says Fox News has been in touch with at least one New Hampshire staffer who is joining the Rick Perry campaign.

Original post: Michele Bachmann's five-person New Hampshire team just quit en masse because in the words of Manchester TV station WMUR they felt "constantly betrayed and even lied to." It's not clear from James Pindell's report, which is behind a paywall, what exactly they're so upset about. He writes that they are still big fans of Bachmann: "They stress that this has nothing to do with their devotion to the candidate. In fact, the staff was going to leave the campaign much earlier, but did not because they felt it wasn’t the best for the candidate." But it sounds like Bachmann's absence from the state while she focused on Iowa played a part. Pindell writes: "Bachmann came to the state last week for the Dartmouth debate. It was her first trip to New Hampshire since late June, and it was the final straw for the local staff." Bachmann, for the record, blames her absence in the state because of the debt-ceiling debate. "You didn't see me a lot here in New Hampshire and I'll tell you why: It's because my first duty was to go back to Washington, D.C.," she told New Hampshirites last week, according to the AP.
