Late last year, U.S. Rep. Michele Bachmann filed a 2014 campaign committee.

The existence of the committee doesn't necessarily lock the Republican into vying again for the Sixth Congressional District. It will allow her to raise campaign cash and do other campaign activities.

Bachmann won her last election by about 4,000 votes, just over 1 percentage point. Just a few weeks later, she filed the 2014 committee.

She is one of five sitting U.S. House members from Minnesota who has filed a statement of candidacy for 2014.

Democratic U.S. Reps. Tim Walz, Keith Ellison, Rick Nolan and Collin Peterson have also filed committees for the next election cycle, and U.S. Sen. Amy Klobuchar, a Democrat, has filed a committee for 2018, the next year she would be up for re-election. U.S. Sen. Al Franken, also a Democrat, has had a 2014 campaign committee on record since early last year.

U.S. Reps. John Kline and Erik Paulsen, both Republicans, and U.S. Rep. Betty McCollum, a Democrat, have not yet filed re-election committees, according to Federal Election Commission filings.

The non-filing does not mean they will not run again, just as the filings do not guarantee a run.

Here's Bachmann's filing:
