Talk about stealing the show. Michele Bachmann used the GOP debate this evening in New Hampshire to announce that she's an official presidential candidate. Politico has more:

Michele Bachmann said on stage just now, in a deliberate bit of stage-stealing, that she's filed her papers and officially become a candidate for president.

Two sources close to Bachmann told me today that tentative plans had been laid to stage the formal announcement -- she'd said she will announce in her native Waterloo, Iowa -- as soon as this Wednesday, though Ed Rollins said the plans aren't set.

The Hill sheds more light on Bachmann's campaign plans:

The Minnesota lawmaker had made rumblings to suggest that she would announce during a trip to Iowa, but instead chose to do it in New Hampshire, the first-in-the-nation primary state.

Bachmann has some campaign infrastructure in place; her chief of staff stepped down earlier this month to take a role with the campaign, and Ed Rollins, a veteran GOP strategist who'd served in the past as a strategist for former Arkansas Gov. Mike Huckabee (R), has also signed on to help Bachmann
