Two Democrats are tossing their hats into the special election race in South Carolina’s 1st District — including the sister of comedian Stephen Colbert. While the chances that a Democrat could flip the heavily-Republican coastal seat are slim, each candidate has the ability to make the race interesting.

Elizabeth Colbert-Busch, the sister of the Comedy Central TV-show host, plans to file paperwork to make her candidacy official on Tuesday, according to reports in the St. Andrews Patch and The Washington Post.

Colbert-Busch works at Clemson University as director of sales and marketing for the Wind Turbine Drivetrain Testing Facility. Given her brother’s connections to Hollywood, it’s likely that she won’t have much trouble raising money for her bid.

Meanwhile, wealthy businessman Martin Skelly on Friday also announced his candidacy for the special election to fill the seat formerly held by now-Sen. Tim Scott, a Republican.

“After witnessing this chaotic Congress — and hearing about too many businesses that won’t invest in our economy because of the dysfunction, I decided it’s time to do my part,” Skelly said in a statement. He said he has seeded his campaign account with a $250,000 loan.

A number of Republicans are running for the seat, the most prominent of which is former South Carolina Gov. Mark Sanford. He begins the race as the front-runner.

The special primary is scheduled for March 19. If no candidate gets more than 50 percent of the vote, a runoff will be held April 2. The special election will be held May 7.

The 1st District, which snakes along the Atlantic Ocean from Hilton Head to north of Charleston, re-elected Scott to his second term in 2012 with more than 62 percent of the vote. According to numbers crunched by the Daily Kos website, GOP White House nominee Mitt Romney won the 1st District with 58 percent of the vote in November.
