As the state Senate District 42 race reaches the homestretch, the three candidates are taking markedly different approaches to turning out their vote.

Democrat Marlon Kimpson is holding a “rise up and vote” rally and fish fry at noon Saturday at Charleston’s International Longshoremen’s Association Hall on Morrison Drive.

A gospel choir and several Democrats, including 2014 gubernatorial hopeful Vincent Sheheen, are expected to join him.

It’s less clear what Republican Billy Shuman is doing: He has not returned calls, nor has he filed his required campaign disclosure form outlining his fundraising and campaign spending.

His campaign has been sending out mail noting that he has been endorsed by such prominent South Carolina Republicans as Gov. Nikki Haley and U.S. Sen. Tim Scott.

In one mailer, Haley encouraged Republicans to vote for Shuman because he would help pass strong ethics reform. Shuman already has racked up more than $110 in ethics fines because he has failed to turn in his pre-election campaign disclosure forum as required.

Kimpson said he would not speculate why Shuman hasn’t filed, “but I can tell you if he has received notification, which I believe he has, it is a reckless disregard of the rules. I think that’s something for voters to consider. Ethics is a major issue in this state.”

Charleston County GOP Chairman John Steinberger said Friday he has talked to Shuman and said Shuman will file his campaign-disclosure form before Tuesday’s election, adding, “I couldn’t tell you exactly when.”

“He’s working hard,” Steinberger said of Shuman. “He’s knocking on lots of doors, talking to lots of people.”

Libertarian candidate Alex Thornton, a professional photographer making her first bid for office, said Friday she is keeping busy doing radio interviews and going door to door in the district.

“I want to end the state income tax,” she said. “There are a lot of other taxes that our state receives. Last year, 88 percent of our revenue came from outside the state income tax.”

The polls open in the race from 7 a.m. to 7 p.m. on Tuesday.
