Let me preface this like by saything: I, like most Americans, definitely don't want to see a Bachmann presidency. However, I'd happy accept her as the GOP nominee, and think she could be to the United States what Christine O'Donnell was to Deleware.
If she wants to become President, during the next debate I think she should make a statement to this effect:
"In the past six years, we've gone through three 'change' elections and the leaders of the House and Senate haven't changed through any of them. Last year, in the midst of a ground-swell movement aimed at returning us to our founding principles, we were told that Tea Party activists could trust the Republican party to do what was necessary to solve the out-of-control government spending and stop the growth of our national debt. Then when it came time to turn words into action we had one GOP leader suggest we actually give Barack Obama more power so he could raise the debt whenever he wanted, and another that agreed to the end of the Bush tax cuts and a host of other job-killing tax hikes. That's not what we voted for, and it's not what the American people want! It's time that we give real change a try!"

If she does this I think it would help her win another debate- and help Democrats in the process.
