The first female contender to enter the 2012 race, Bachmann announced her bid during a Republican presidential debate in New Hampshire. The third-term Minnesota congresswoman has been leaning heavily toward a run over the past few months, visiting early primary states, raising money and railing against President Barack Obama.
"Our country needs a leader who understands the hardships that people across America have been facing over the past few years, and who will do what it takes to renew the American dream. We must become a strong and proud America again, and I see clearly a better path to a brighter future," Bachmann said in a statement issued through her new campaign.
She brings high energy, charisma and proven fundraising ability to the Republican race to nominate a challenger to Obama. She also is known for unyielding stances, biting commentary and high-profile gaffes.
Bachmann is attempting the rare leap from the U.S. House to the presidency.
Despite having low seniority and few policy accomplishments, she has risen to prominence in Washington in part by her frequent television appearances and willingness to attack Obama in sharp terms. Her popularity with tea party activists and her credentials as a social conservative make her a credible threat to other candidates courting conservatives who make up the core of the Republican Party. Her impact may be felt most in Iowa, the first stop in the nomination battle where Christian evangelicals dominate.
While she hasn't built the broad campaign infrastructure of some GOP rivals, she has gradually patched together a blend of tested and fresh-but-determined advisers. She's also shown an ability to raise money from a network of small-dollar donors, including $13.5 million she put toward the nation's most expensive House race of 2010.
Bachmann spent the bulk of her political career in Minnesota and Washington as a minority party member, reveling in her role as a fierce voice of the opposition. She didn't let up when Republicans gained control of the U.S. House last fall, enhancing her standing through public breaks with party leaders after she was denied a place in caucus leadership.
The camera-friendly congresswoman has irked some party leaders by grabbing at the spotlight, such as the alternate televised response she delivered to Obama's State of the Union speech this winter.
Her willingness to speak her mind - she once accused Obama of running a "gangster government" - has brought her both loyal fans and plenty of critics.
Since first hinting at a presidential campaign ahead of an Iowa speech in January, she has made sustained trips there and to New Hampshire and South Carolina, all places with an outsized voice in the nominating process. She previously told reporters she would announce her intentions this month in her birthplace of Waterloo, Iowa.
Other full-fledged candidates include former Govs. Mitt Romney of Massachusetts and Tim Pawlenty of Minnesota, former House Speaker Newt Gingrich, Texas Rep. Ron Paul, former Pennsylvania Sen. Rick Santorum and businessman Herman Cain.
Still a possibility is Sarah Palin, the former Alaska governor and 2008 Republican vice presidential nominee. Palin assisted Bachmann in her 2010 race. And while the two deny any inherent rivalry, the potential they may both run in 2012 has already stirred up such talk.
Bachmann, 55, enters as a definite factor in Iowa's caucuses, not just because it is her native state and now neighbor. Despite her status as an elected official, she is attractive to GOP activists looking for a candidate with outsider appeal. She particularly resonates with the conservative coalition that led former Arkansas Gov. Mike Huckabee to a 2008 caucus win.
She has vigorously courted evangelical pastors during her early trips to Iowa. Bachmann has also landed the support of up-and-coming GOP players, including state Sen. Kent Sorenson, an ardent social conservative.
Sorenson is lined up to run Bachmann's Iowa campaign. Bachmann has also signed a former top deputy to Huckabee's 2008 Iowa campaign. However, it's not clear whether those hires and Bachmann's popularity with this segment of the caucus electorate would necessarily translate into organizational strength.
Former Massachusetts Gov. Mitt Romney's decision to bypass the Iowa GOP's presidential straw poll in Ames gives Bachmann a stronger chance for a breakthrough moment a couple of months out of the gate.
Before politics, Bachmann was an attorney who at one point chased tax cheats for the federal government. A mother of five and foster parent over the years to more than 20 girls, Bachmann dove into public life during a fight over Minnesota school standards. She spent six years in the Minnesota Senate before winning an open seat Congress, where she's been since 2007.
Bachmann's husband, Marcus, runs a Christian-based counseling clinic.
