Michele Bachmann is continuing her push to win next month's Ames Straw Poll, today releasing her first ad in Iowa. It focuses on her just-say-no approach to government spending.

"I know we can't keep spending money that we don't have," she tells the camera, against the backdrop of an upbeat acoustic guitar. "That's why I fought against the wasteful bailout, against the stimulus."

"I. Will. Not. Vote. To Increase the debt ceiling," she says.

Negotiations to increase the federal borrowing limit continue between the White House and congressional Republicans. The terms of any potential deal remain unclear.
