Arrington take a hike ad

Republican Katie Arrington's newest TV ad takes a swipe at the most infamous part of U.S. Rep. Mark Sanford's past: His extramarital affair forever tied to the euphemism "hiking the Appalachian Trail."

Arrington, who is challenging Sanford in South Carolina's 1st Congressional District GOP primary, released the attack ad Monday. 

The 30-second spot called "Take a Hike" opens with Arrington walking along an undisclosed trail head. Within the first seconds she digs at Sanford for his 2009 affair.

"Mark Sanford and the career politicians cheated on us," she says. "We sent him to do a job but he left his post and set off down a long trail towards obstructionism."

The one-term Statehouse lawmaker from Summerville then goes on to make claims she frequently makes in her campaign: Her support of President Donald Trump, her commitment to cut spending and her pledge to send career politicians home.

She closes the ad with a Southern zinger: "Bless his heart, but it is time for Mark Sanford to take a hike — for real this time."

In 2009, Sanford, then-governor of South Carolina, was caught having an extramarital affair after his office lied and said he was "hiking the Appalachian Trail."

Sanford has faced this part of his past in three previous elections: A special election in 2013, and his subsequent reelection in 2014 and 2016.

Arrington's campaign said the ad will air on broadcast TV, cable and online.

The ad is the second time Arrington has gone negative in her messaging. In late April, she began airing a 30-second attack ad that used Sanford's own critical words about Trump against him.

The Sanford campaign did not return a call seeking comment.
