It’s primary day today, folks. With crowded primary elections set up for state superintendent, lieutenant governor, and U.S. Senate on the Republican side, state elections officials say historically, about 20% of voters turnout for midterm primaries, but without a major draw at the top of the ticket — Dem and GOP candidates for governor are unopposed, as are many congressional seats — we’ve got our chips on voter turnout closer to 15 percent.

It’s hard to believe that it was four years ago today that accidental candidate Alvin Greene was selected by the voters of South Carolina to be the Democratic nominee for the U.S. Senate, beating sitting Charleston County Councilman Vic Rawl. But who’da thunk it, one cycle later, Greene’s opponent Jim DeMint is no longer an elected official and we’re voting once again this year to fill that seat as appointed U.S. Sen. Tim Scott seeks his first proper election to the office.

Polls are open tonight until 7 p.m.
