(CNN) - White House hopeful Michele Bachmann on Wednesday mailed the paperwork needed to get on the ballot for New Hampshire's first-in-the-nation presidential primary.
The announcement comes days after her five-member New Hampshire campaign staff resigned en masse, accusing the Minnesota congresswoman's national campaign handlers of being "rude, unprofessional, dishonest, and at times cruel."
Bachmann's top spokesperson Alice Stewart downplayed the claims in an interview with CNN on Monday.
"That's unfortunate. They want to call names, that's their prerogative. We wish them the best," Alice Stewart said on CNN's "John King U.S.A."
According to a new CNN/Time/ORC International poll released Wednesday, Bachmann placed seventh in the GOP field in New Hampshire, taking top choice among 2% of registered Republican and independent voters who voted in the 2008 primary.
Her campaign mailed the papers along with the $1,000 filing fee to the Secretary of State's office in Concord on Wednesday, ahead of the filing deadline on Oct. 28.
"I'm thrilled to take this important step on the road to securing the Republican nomination for president," Bachmann said in a statement. "The people of New Hampshire are a vital part of the process and I look forward to sharing my message with more people in the Granite State."
Former Massachusetts Gov. Mitt Romney, former Utah Gov. Jon Huntsman, former Pennsylvania Sen. Rick Santorum, and former House Speaker Newt Gingrich all delivered their papers in person to the Secretary of State's office.
Former Godfather's Pizza CEO Herman Cain and Texas Rep. Ron Paul both filed their paperwork by proxy.
Texas Gov. Rick Perry is expected to file in person Friday at 12:15 p.m.
