Vice President Joe Biden says the primary victory of a gun control advocate to represent Illinois in Congress sends a message that voters won't stand for inaction in response to shooting violence.

Robin Kelly was elected Tuesday as the Democratic nominee to replace former Rep. Jesse Jackson Jr. after running on gun control. New York City Mayor Michael Bloomberg's political fund poured $2 million into television ads against an opponent who had been highly rated by the National Rifle Association.

Biden told a gathering of state attorneys general at a Washington hotel Wednesday that voters in the Chicago-area district "sent a clear unequivocal signal" to the NRA and politicians nationwide. Biden said, quote, "The message is there will be a moral price as well as a political price for inaction."
