Voters go to the polls Tuesday to vote in the Democratic primary for a seat that belonged to a woman who died last year, and Greene, the improbable candidate who faced Republican Sen. Jim DeMint in the general election in November, is on the ballot.

In December, Greene paid the $165 fee to the Clarendon County Democratic Party to enter the race, just five minutes after the filing period opened. The special election is set for April 5.
