The debate, sponsored by conservative site Townhall.com, saw Bachmann swimming in the shallow end of the Republican pool against Newt Gingrich, Rick Santorum, Herman Cain, Thad McCotter and Gary Johnson.
With Twitter, Bachmann's finally found a medium that doesn't let her blurt out wild allegations, or misstate facts. Plus, she's not going to get any questions about her headaches, her husband's anti-gay clinics, or any crazy or stupid thing she might have said or signed.
Interestingly, the one live question Bachmann got came from a mysterious person who apparently didn't ask it.
Bachmann and Gingrich, a 68-going-on-11 year old geek, proved most adept at using the Twitter format. At one point, Gingrich tweeted a bitly.com link to a campaign video, which was technically outside the rules of the all-Twitter debate.
Bachmann showed off an understanding of hashtags, and used abbreviated write-arounds to keep all the amazing things in her head to less than 140 characters.
But when it came time for Bachmann to take a tweeted question from the audience, a curious thing happened. First, moderator S.E. Cupp sent along the question:
Bachmann's reply was bold, brief, and short on verbs.
There's only one problem. The question didn't come from @Ljordan, who apparently hasn't sent out a single tweet yet. So who is @Ljordan, and who really asked this question? We might never know, or care.
This fake Twitter question will surely become the scandal that brings Michele Bachmann down.
Perhaps least impressive was McCotter, who completely misunderstood the format, sending out long, multi-tweet paragraphs that got sliced up by other candidates' answers, leaving odd fragments dangling without a beginning or end.
Another notable performance came from Rick Santorum, who apparently answered questions by jamming his forehead into the keyboard.
The convenient format that allowed Bachmann to answer a softball question -- from a person who didn't actually ask it -- also let her dodge real, pressing queries like this one.
But the question of the day came as the first ever Twitter debate wound down.
Why did you agree to do this? And do you regret it now? #140townhall
These are great questions. Though, come to think of it, it's not clear whether he's asking about the Twitter debate or running for president.
