The South Carolina State Election Commission will not investigate Democrat Alvin Greene’s controversial victory in last week’s Senate primary.

"The state election commission sees no reason to initiate an investigation into our voting system," Chris Whitmire, a spokesman for the commission, told The Ballot Box. "We have full confidence in the reliability and accuracy of the state's voting system, and we have nothing to indicate there was any voting system failure on June 8th. The system has performed accurately and consistently."

Greene won the June 8 primary with 58 percent of the vote, defeating Vic Rawl, a Charleston County councilman, by more than 30,000 votes.

House Majority Whip James Clyburn (D-S.C.) has called Greene a "plant" and repeatedly called for an investigation into his win.

Despite making several TV appearances to talk about Greene's victory, Clyburn hasn't contacted the commission, according to Whitmire.

"We've had no contact from the candidates in the U.S. Senate race and no contact from Congressman Clyburn," he said.

The watchdog group Citizens for Responsibility and Ethics in Washington has asked state Attorney General Henry McMaster to investigate whether Greene "accepted an inducement" to run. The group also complained to the Federal Election Commission, noting Greene hasn't filed the proper paperwork.

On Tuesday, Rawl said he also planned to file a "protest" against Greene's win.

Rawl will meet with the state Democratic Party's executive committee Thursday where he's expected to call for a new election based on supposed irregularities in the voting machines.

If the state party calls for a new election, the SEC would seek legal advice to help determine the manner in which any new primary would be conducted, Whitmire said. It's unclear when the vote would take place.

Regardless of the outcome of the meeting, South Carolina has another round of voting coming up on June 22, when the Republican gubernatorial primary and several others will go to a runoff.
