Sanford took his humiliation. With little fuss he stepped down as governor. He laid low for 4 years. He offered himself to the public once again at the congressional district level where he had begun his political career in 1994.
ADDED: From the above-linked article:
A turning point in the race came two weeks ago, when Sanford held a mock debate with a cardboard cutout of House Minority Leader Nancy Pelosi, implying that the California Democrat — persona non grata in conservative South Carolina — was a stand-in for his Democratic opponent.Be careful with mockery. It's a wild beast. Once unleashed, who knows what it will do? Liberals may think their side owns comedy. And not just when their candidate is the sibling of political humorist.
The former governor endured days of derision from the press for the move — Mark Sanford, once regarded as a viable potential presidential candidate, was debating a piece of cardboard.
But behind the scenes, Sanford’s aides grinned: Every time a reporter put “Pelosi” and “Colbert Busch” in the same sentence, the Republican was winning. And some Democratic aides began to worry, too.
