Following revelations that his ex-wife accused him of trespassing on her property earlier this year, former South Carolina governor Mark Sanford (R) has lost the support of his national party.

The news comes as controversy continues to swirl around Sanford and his personal life -- a process that began with his well-publicized 2009 affair but was inflamed, the Washington Post has learned, when one of the Sanfords' sons met Mark Sanford's former mistress for the first time the night he won the GOP nomination.
