South Carolina Sen. Lindsey Graham, who is facing a few Republican primary challengers, released his first TV and radio ads of the year on Tuesday.
The ads work to burnish Graham's conservative credentials with four months left until the June 10 primary. The ads are backed by a six-figure buy and will run statewide for more than a week, according to a release.
The TV ad notes Graham "opposed Obamacare from Day One," "led the fight on Benghazi," and is "a conservative leader who gets things done."
Listen to "Conservative":
Graham entered the cycle as one of the most vulnerable Republican incumbents to a conservative primary challenge, but a few of his colleagues are in a far more tenuous place than he is at this point. Graham continued his strong fundraising in the fourth quarter, bringing in more than $1.3 million and ending 2013 with $7.6 million in cash on hand.
His foes have yet to make a fundraising surge or invite much outside help from big-spending super PACs. Still, if Graham is held below 50 percent in the primary, he and the second place finisher will face off in a June 24 runoff.
The general election is rated a Safe Republican contest by Rothenberg Political Report/Roll Call.
