Bachmann says "I'm in it for the long haul."
Bachmann tells CBS's "The Early Show" she a viable candidate, noting she won the Iowa straw poll. That test of strength happened on the same day that Perry, the governor of Texas, got into the race.
Bachmann tells interviewers she isn't participating in this weekend's Florida straw poll, saying the balloting there is among a much narrower band of prospective voters in Iowa. She stresses that "we're in it for the marathon." The congresswoman also says she's working hard on fundraising efforts and says the party needs a candidate "who understands the economy and job creation."
