South Carolina would create an 11-day window for early voting under legislation heading to the House.
The House rejected early voting efforts last month when it was tied to a bill requiring voters to show state- or federal-issued photographic identification. The Senate on Wednesday added the measure to a bill dealing with primary elections.
Columbia Democratic Sen. John Scott said it was a last chance for the House to give voters more time to vote.
The legislation says counties will set up at least one early voting center that would be open at least two Saturdays before primaries and elections. Counties can have up to three early voting centers. Early voting would end three days before the election.
