Mark Sanford: I'm A 'Wounded Warrior,' Scared Of Getting 'Hit Hard' (VIDEO)

Former South Carolina Gov. Mark Sanford (R) has launched a comeback campaign to regain his seat in Congress -- but that doesn't mean he's not apprehensive.

In an interview with Charleston, S.C.'s News 2, Sanford said his biggest fear going into this campaign is the media attention he consistently garners.

“I’m scared to death in human terms. I mean, as I say, I’m a wounded warrior," Sanford said. "I’m going to step out as best I can and try and advance ideas that I’ve long believed in. But it’s not without fear and trepidation because you know you’re going to get hit, and you’re going to get hit hard.”

Sanford officially announced Wednesday that he would enter the race for an open seat in Congress, which he previously held from 1995 to 2001. The seat was vacated when former GOP Rep. Tim Scott was appointed to the Senate. Sanford consulted his ex-wife, Jenny Sanford, an often-rumored political contender, before launching his campaign.

Sanford was caught in a media frenzy in 2009 when his affair with Maria Belen Chapur, an Argentinian woman to whom he is now reportedly engaged, was exposed. The affair led to his divorce from his wife and plenty of public outrage.

Now, Sanford will try for a fresh start, both for his public image and personal career.

"All you can do in life is repent, say you're sorry and get up the next day. You've gotta climb back up and you've gotta step forward as best you can based on what you believe in your heart," Sanford said. "We all hope for redemption, we all hope for second chances."
