Disgraced politico ex-Governor of South Carolina MARK SANFORD, who was caught cheating on his wife with a South American hottie, is BACK — with a vengeance.

Sanford was a hot button ticket for Republicans who saw him as a presidential contender until he revealed in 2009 that he had an affair with an Argentine woman.

THAT put him on the national landscape along with John Edwards – but for all the wrong reasons.

Sanford has since become engaged to his South American beauty after finishing out his second term as Governor in 2011.

But now Sanford, who was a strong fiscal conservative, said he wants to return to Washington because out of control spending is (yup) out of control.

Sanford is seeking the 1st District seat on South Carolina’s coast.

Is there hope yet for other shamed pols — sext-maniac ANTHONY WEINER and  ring-a-ding JOHN EDWARDS?
