As Tuesday's primary approaches, state Rep. Chip Limehouse, R-Charleston, a candidate for the 1st Congressional District nomination, is hitting Teddy Turner hard in a new ad.
Turner has pushed back against both Limehouse and former state Sen. John Kuhn, who also seeks the GOP nomination, in recent ads and mailers.

Internal polling from various candidates shows former Gov. Mark Sanford will receive the most votes and make a runoff. But it's still up in the air who his GOP challenger will be. Kuhn, Limehouse and Turner are all strong possibilities, according to polling.
