A California-based political action committee targeting U.S. Rep. Michele Bachmann plans to open an Anoka County office and team with already-established in organizations in Minnesota in an effort to oust the three-term congresswoman.

CREDO SuperPAC has added Bachmann to a list of conservative Republican U.S. House members it wants to see defeated in November after reviewing results from last week's primary election, citing the numbers as proof that she's vulnerable and not guaranteed to win re-election.

Bachmann has come under fire this summer for alleging that Huma Abedin, an aide to Secretary of State Hillary Clinton, and U.S. Rep. Keith Ellison of Minnesota have ties to Egypt Muslim's Brotherhood.

"CREDO SuperPAC will be mobilizing local volunteers to ensure voters know just how extreme Bachmann is before she does any more damage ...," said Becky Bond, the group's president.

With its reluctance to spend money on radio and television ads, CREDO has taken a different approach than many super political action committees. The group plans to spend about $3 million nationwide to hire staff and place them in targeted congressional district, such as Bachmann's, where the workers organize door-knocking and phone banks campaigns that target the incumbents and their voting records.

The fund, founded by San Francisco-based cell phone company CREDO Mobile, is also targeting Rep. Chip Cravaack as part of its "Take Down the Tea Party Ten" campaign. As part of their campaign against Cravaack in the 8th congressional district, CREDO SuperPAC has an office in Duluth with four staff members that have helped form constituent groups such as Seniors Against Cravaack and Women Against Cravaack.

CREDO SuperPAC will open a similar office in Bachmann's district, likely in Anoka County. An announcement on the office's location could come early next week, Bond said.

Bachmann is seeking a fourth term in the 6th congressional district, where Democratic businessman Jim Graves is challenging her.

"It's not surprise that a group of radical San Francisco liberals are coming to the aid of ... Jim Graves," said Bachmann campaign manager Chase Kroll. " ... but at the end of the day, Minnesotans support Michele Bachmann because they know she's an independent voice, fighting for them to bring about a smaller government and a more affordable way of life."

CREDO SuperPAC has no plans to directly aid Graves, Bond said.

Alliance for a Better Minnesota, a group backed financially by labor unions and the former wife of Gov. Mark Dayton, will be one of CREDO SuperPAC's allies in the campaign against Bachmann. The two groups have also teamed up on projects in the 8th district.
