U.S. Rep. Michele Bachmann is enlisting the help of a fellow controversial conservative female politician in her re-election bid.

Former GOP vice presidential candidate Sarah Palin will be in Minnesota April 7 to campaign for Bachmann, the Republican congresswoman's campaign announced.

"There is absolutely no one more in tune with the hearts and minds of everyday Americans than Gov. Palin, and I'm excited to welcome her back to our beautiful state this spring," Bachmann said in a statement.

A Bachmann spokesman said campaign plans are under way; no details were released.

Palin, the former Alaska governor, is campaigning for conservative candidates on the ballot this fall as political observers speculate whether she will make her own White House run in 2012. She was Sen. John McCain's running mate in 2008. She announced Wednesday she also will campaign for McCain in his home state of Arizona.

Bachmann's Palin announcement came as Republicans celebrated a surprise GOP Senate victory Tuesday in a Massachusetts special election.

"The American people have spoken, and the momentum is clearly at the backs of conservatives heading into the 2010 elections," Bachmann said in the release.

Bachmann's 6th District includes Woodbury and stretches from the east metro northwest to St. Cloud. She is seeking a third term.

Two Democrats - state Sen. Tarryl Clark of St. Cloud and Maureen Reed of Stillwater - are running to replace Bachmann.

"This is just another example of Bachmann trying to enhance her national star power rather than working on preventing home foreclosures, creating jobs or offering solutions to address our health care crisis," Reed spokesman Trevor Willett said. "Palin, like Bachmann, brings polarizing rhetoric, intent on dividing people instead of bringing them together."

Clark's campaign also said the announcement was proof Bachmann is more interested in furthering her personal agenda than representing her district.

"Instead of bringing jobs and investment to the district, she's bringing Sarah Palin to build her own fundraising coffers and advance her own national conservative credentials," Clark spokeswoman Andrea Mokros said.
