York County Council incumbents Buddy Motz and Curwood Chappell defeated Republican primary challengers Tuesday, paving the way for their return to the board.
Neither faces an opponent in November, so they're expected to return to the council.
Incumbents Tom Smith, a Republican, and Roy Blake, a Democrat, will have runoffs June 24.
All results are final but unofficial until certified on Thursday.
The primary comes four and a half months after the S.C. presidential primary.
U.S. Sen. Lindsey Graham fended off Republican challenge Buddy Witherspoon, a retired orthodontist and former Republican National Committee member, by a 67-33 percent margin with 89 percent of the precincts reporting.
Witherspoon criticized Graham as being too liberal for South Carolina and “joined at the hip” with John McCain, the presumptive GOP presidential candidate.
Graham will face either Democrat Michael Cone of Mount Pleasant or North Myrtle Beach engineer Bob Conley. The race was nearly evenly split and headed toward a recount.
