The Democratic National Committee is running a Spanish language ad on radio stations in North Carolina and Georgia, where there are competitive U.S. Senate races.
"Republicans think we're going to stay home," the ad says. "It's time to rise up."
Democrats see opportunity in Southern states with fast-growing minority populations and an influx of people relocating to the Sun Belt. In Georgia, there's a push to register new voters in hopes of turning a red state blue.
