Michelle Nunn, the likely Democratic nominee for Senate in Georgia, has released her first 30-second TV ad of the campaign. Nunn is the daughter of former senator Sam Nunn, but the ad seeks to introduce her more broadly to voters in Georgia.

“Some people ask me why, with all the dysfunction in Washington, I’m running for Senate,” Nunn says in a voiceover. “In the end, I think it comes down to being an optimist.”
