On Tuesday, voters will decide between Sanford and Democrat Elizabeth Colbert Busch in a special election in South Carolina's first Congressional district, two days before the former governor's court appearance. The House Republican campaign committee dropped financial support for the former governor after allegations of the trespassing incident surfaced. 

But a PPP poll released Sunday night found Sanford with a one-point lead over Colbert Busch and momentum in the race against comedian Stephen Colbert's sister.
