Michele Bachmann is in her hometown today, hoping to sway huge numbers of still-undecided voters to support her in the Iowa caucuses tonight. The AP says a poor showing could sink her campaign, and the latest poll in the Des Moines Register doesn't have good news. And ABC tries to answer the question on many people's minds: What's a caucus, anyway?

In an interview with Bloomberg's Al Hunt, Michele Bachmann said any of the current Republican candidates for president will be "acceptable to the American people" but said "America had their chance with the perfect candidate."

The latest Iowa poll shows Bachmann is the preferred Republican presidential candidate of eight percent of respondents. That's a far cry from the 22 percent she polled in June and from the 23 percent of new poll leader Herman Cain. In an appearance on ABC, Bachmann downplayed the importance of polls.

The Minnesota Congresswoman praised her former Republican presidential opponent during an interview on NBC's Meet the Press Sunday. Bachmann dropped out of the race for the White House in January and is now seeking another term representing Minnesota's Sixth Congressional District.

In an interview, a Muslim Brotherhood leader in Egypt’s Daqheleya province, Ibrahim Ali Iraqi, says a claim by Rep. Michele Bachmann, R-Minn., that the group had infiltrated the U.S. government is "ridiculous." “The Muslim Brotherhood can’t even penetrate the Egyptian government,” he says.

Voters in Minnesota's sixth district are wondering out loud if their congresswoman will run for re-election under new district lines, challenge Amy Klobuchar for U.S. Senate, or consider a vice presidential bid
