Minnesota Rep. Michele Bachmann staff continues to quit on her. Her fifth chief of staff and her finance director bailed on her on Tuesday

Two top staffers to Minnesota Rep. Michele Bachmann left their jobs Tuesday, leaving the confrontational congresswoman without a chief of staff in her House office or a finance director for her reelection campaign.

Ron Carey, a former chairman of the Minnesota Republican Party, becomes the fifth chief of staff to leave Bachmann's office since she was first elected just four years ago.

"Congresswoman Michele Bachman thanks Ron Carey for his service to her and to the district and wishes him the best for his future," Bachmann spokeswoman Rachel Horn said in a statement. Bachmann's office also announced that Andy Parrish, a Minnesota AARP official who has worked for Bachmann before, will rejoin her staff as a senior adviser.

The news of Carey's departure came just hours after Zandra Wolcott, Bachmann's top fundraiser, said she was leaving her post at the campaign, offering only a vague explanation for the move.

"I am leaving the campaign," said Wolcott, a successful Minnesota operative who was a lead consultant for President George W. Bush's campaign in the state.

"It's just time to move on, I have other things to do here in Minnesota."

Wolcott would not say whether she decided on her own to leave the job or if the campaign asked her to leave.

Bachmann is running against Democratic state Sen. Tarryl Clark in a race that's quickly becoming one of the nation's most expensive. Bachmann has raised more than $4 million for her campaign and Clark has brought in over $2 million, including $910,000 in the last quarter.
