In her first ad of the election cycle, unveiled Thursday, Democratic Senate candidate Michelle Nunn introduces herself to Georgians as an "optimist" and touts her work with former President George H.W. Bush to boost her centrist credentials.

"Some people ask me why, with all the dysfunction in Washington, I'm running for Senate," Nunn says in the 30-second ad. "In the end, I think it comes down to being an optimist."

"I'm optimistic about Georgia's future," she adds.

Nunn, the daughter of former Georgia Sen. Sam Nunn and a star Democratic recruit in this midterm election cycle, also describes her tenure as CEO of the Points of Light Foundation, a nonprofit organization founded by former President Bush.

Nunn is pictured with Bush at one point during the ad — consistent with her strategy so far to tout her association with the former president and other Republicans in hopes of establishing a reputation as a political moderate in a Republican-leaning state.

Nunn will face the winner of a crowded Republican primary race to be held May 20, with a potential runoff in July.

Public polling has so far been scarce for potential general-election match-ups, but one recent survey by an Atlanta TV news station found Nunn tied with all would-be Republican opponents.
