CHARLESTON, S.C. (AP) -- Former South Carolina Gov. Mark Sanford is looking to clear a second hurdle in his bid for a political comeback.
Sanford was the top vote-getter in the March 19 Republican primary for his old congressional seat in the state's 1st District. On Tuesday, he faces Curtis Bostic in the Republican runoff.
The winner meets Elizabeth Colbert Busch, the sister of comedian Stephen Colbert, in the special election in May.
Sanford is trying to make a comeback after he disappeared from the state in 2009, misled his staff about his whereabouts and then returned to admit an affair with an Argentine woman. They are now engaged.
Bostic says that left Sanford a compromised candidate and that he is the best choice to keep the seat out of Democratic hands.
