Sanford in February vetoed a bill that would have combined Charleston County's two voting offices into one. Lawmakers pushed the bill to reform the election process in Charleston County, which in November was plagued by long lines and a lengthy vote count.
The veto upset a number of lawmakers, who said Sanford did not contact members of the delegation to inform them of the veto.
Sanford said he didn't oppose combining the offices, but the bill was local legislation targeted at a specific county, and therefore, unlawful special legislation.
Republicans in the Charleston County delegation had a difficult time getting the necessary support to override the veto. But on Tuesday, members agreed. They voted 14-0 to override the veto, prompting House Speaker David Wilkins to joke, "Something strange is going on in Charleston County."
"I commend you for working out your differences so we don't have to hear from you anymore," said Wilkins, R-Greenville.
