"I’m the mother of a nine-year old and a six-year old and I want a better future," Ayotte says in the ad. "I support Scott Brown because I know that he's for fiscal responsibility, accountable government and, finally, a health care plan that works for all of us."
Brown is in a competitive race with Sen. Jeanne Shaheen, the Democratic incumbent, and some polls have lately shown the race tightening.
As New Hampshire's top Republican elected official, Ayotte has lent her local star power to Brown's cause on the campaign trail, but this marks her first appearance in one of his TV ads.
Earlier this year, Ayotte also officiated the wedding of Brown's daughter, Arianna.
