Bachmann files by mail for presidential primary
Her one-page declaration of candidacy arrived at Secretary of State William Gardner's office early Wednesday.
Bachmann late last week lost her five-person New Hampshire campaign staff in an internal dispute. She has focused on winning the Iowa caucus.
Bachmann's candidacy soared after a nationally televised debate in June, but fell sharply during the summer.
After months of absence from the state, Bachmann returned in early October telling a small group of Tea Party supporters, "I want to be your sweetheart here in New Hampshire."
The filing period for primary candidates closes Friday.
