Republican state Rep. Chip Limehouse of Charleston formally entered the 1st Congressional District race to fill the vacancy left by Tim Scott’s elevation to U.S. senator.

“I’m running for Congress. Period,” said Limehouse, who has been in the Legislature since 1995.

In other 1st District events, former state treasurer Thomas Ravenel responded on his Facebook page to speculation that he might be interested in the seat after his name was used in a recent poll.

“Yes, I am considering a comeback but I’m not sure if the timing of this race is right for me,” he wrote. “Anyway, the filing deadline is not until January 28 so that’s 17 days for me to make up my mind.”

He did not immediately respond to a phone message. Ravenel resigned his post as treasurer after being caught up in a cocaine scandal.

Also today, the Weekly Standard, quoting unnamed close sources, said former Gov. Mark Sanford will announce early next week that he is in the race for the seat he once held. And former state Sen. John Kuhn opened a campaign office today at 39 Broad St.
