Each of Iowa's 99 counties is likely to hear from Republican presidential hopeful Michele Bachmann by the end of December.
Bachmann's campaign said Monday that she plans to spend 10 days crisscrossing the state and will begin Friday in northwest Iowa. With a break for Christmas, Bachmann's bus tour is expected to stop in every Iowa county by Dec. 28.
The Minnesota congresswoman is hoping to pull off a surprise win in the first caucus state.
Bachmann won a nonbinding Iowa GOP straw poll in August but her standing has slipped since then. Polls show former House speaker Newt Gingrich leading his rivals in the state.
Iowa opens the GOP nominating push with its precinct caucuses in about three weeks, on Jan. 3.
