10 December 2014: South Carolina Senator Vincent Sheheen (Democratic) prefiled SB 204. The bill requires that parties receiving 5% or more of the Presidential vote in the last Presidential election agree on a single date for the Presidential primaries. If the parties cannot agree, the primary would be held on (1) the second Tuesday in June or (2) on a date chosen by each party. The latter would require each party to pay for its primary.
