Michele Bachmann’s (R-Mars) chief of staff is bailing out, and declines to say why.

The aide who helped turn Rep. Michele Bachmann into a controversial mainstay of cable news has informed colleagues that she’s quitting — just as the firebrand Republican congresswoman prepares for her biggest media moment yet.

Multiple sources have confirmed that Michelle Marston, a veteran Hill aide, is leaving Bachmann’s office.

In an e-mail exchange with POLITICO, Marston declined to say why she’s going.

“I’m just not talking about it, and frankly I don’t think there’s a story here,” Marston wrote. “Now, the thousands of people calling our office to tell us [they’re] coming to Capitol Hill tomorrow — that’s a story.”

Marston was referring to the prolific Bachmann’s latest political brainstorm, a “house call” on the Capitol Thursday to which she’s invited Fox News viewers and other conservatives to march with her through House office buildings, “find members of Congress, look at the whites of their eyes and say, ‘Don’t take away my health care.’”

Oh, for Pete’s sake. Meanwhile, anonymous sources muttered:

A conservative Republican House member, speaking on the condition of anonymity, suggested that Bachmann’s views — and her willingness to state them — make it hard for her to keep staff. “When your captain’s crazy, it’s time to find a new ship,” the lawmaker said.

Judge Andrew Napolitano warns Michele to watch out for Nancy Pelosi and her schemes, because she controls the capital and might do anything at all to stop the populist glory of Michele’s “house call.”

Yay! It’s the “Super Bowl of freedom!”
