A Georgia Republican candidate for governor is saying he "won't back down" after outcry over a campaign ad that shows him aiming a shotgun at "a young man interested in one of my daughters."

"I'm conservative, folks. Get over it," he tweeted Tuesday night. 

Georgia Secretary of State Brian Kemp, who is seeking the GOP nomination in the state's May 22 primary, prompts the teenage boy featured in the ad to tout the values of "respect" and "a healthy appreciation for the Second Amendment" before raising the firearm in his direction. 

The ad has prompted outrage from some gun control advocates — particularly in light of the recent Parkland, Fla. shooting that left more than a dozen teenagers dead. 

But Kemp says that anger over the ad simply underscores how liberal "radicals" overreact to gun ownership. 

"The left is FREAKING OUT about our new TV ad, which highlights my 4-Point Plan and underscores my commitment to protecting the 2nd Amendment," he tweeted Wednesday after an appearance on Fox News. "I was on @FoxNews this morning with a message to these crazy radicals: I'm conservative. Get over it!"

Kemp isn't the first candidate in the race to make guns a campaign issue. 

Lt. Gov. Casey Cagle, who is also seeking the GOP nod, promised to "kill" any legislation that would benefit Georgia-based Delta airlines after it cut ties with the NRA.
