While the page with Greene's name says it may be appearing "as a result of draft committees or independent expenditure committees registering with the FEC," commission spokesman Christian Hilland tells TPMmuckraker that the page is likely the result of the South Carolina secretary of state's office providing the commission with a list of names that appeared on the ballot -- not any spending on behalf of Greene.
There are no contributions to Greene listed. A Dem operative familiar with the race tells TPMmuckraker that the FEC page appeared sometime since Saturday.
Hilland also said that candidates are required to file a statement of candidacy (see here) within 15 days of spending more than $5,000 on a campaign. Greene did pay a $10,400 filing fee with the state Democratic party -- but Hilland says that filing fee does not apply toward the $5,000 registration.
Greene's opponent, former state legislator Vic Rawl, did make routine filings with the FEC, which you can see here.
Greene's candidacy is so strange that Rep. James Clyburn (D-SC) today dubbed him a "plant" and called for an investigation. And details of the felony obscenity charge against Greene last year continue to trickle out.
