(CNN) - Despite a last place finish in a key poll two days before the Iowa caucuses, Minnesota Rep. Michele Bachmann vowed Sunday that her supporters will carry her through Tuesday and beyond in the primary and caucus calendar.
Bachmann, who won the Iowa straw poll in August, came in at 7% in the Des Moines Register poll published Saturday night, behind Texas Gov. Rick Perry.
In an interview Sunday with Wolf Blitzer, anchor of CNN's "The Situation Room," the congresswoman said she has seen large and "charged" crowds at recent campaign stops, adding that poll numbers have not been a strong measure of enthusiasm.
She also argued that the nature of the caucuses makes them unpredictable.
"About 40 to 45% of the people in Iowa haven't made up their minds, we don't know who will come to the caucuses [or] who won't." she said on CNN. "You can take poll tests, but everything that matters is who shows up and who do they support."
Bachmann has traveled heavily across the state, and she has repeatedly said Iowans "are going to see a miracle" when the caucuses are over.
Her campaign confirmed to CNN that she'll head to South Carolina before continuing on to New Hampshire after the caucuses on Tuesday, suggesting she considers a strong showing in the Jan. 21 South Carolina primary important to her political future.
On Sunday, Bachmann also reiterated her hope to become "America's iron lady," saying she's the only one with the resolve to carry on "Reagan's legacy" and be "America's Margaret Thatcher."
