The defendants included Greene County commissioners, officials, and employees; a racing commissioner; a member of the board of education; a Eutaw city councilman; and other community leaders.

Six Democrats from Lincoln County, West Virginia, pleaded guilty to charges of participating in a conspiracy to buy votes dating back to 1990. The indictment charged that the cabal conspired to buy votes in every election held between 1990 and 2004, handing out slates listing preferred candidates and using liquor and cash—typically $20 per vote—to seal the deal. They also laid gravel on roads for supporters and fixed traffic tickets.

Paul Schurick, former campaign manager to Maryland Gov. Robert Ehrlich, a Republican, was convicted of election fraud after approving a robocall to black voters telling them not to vote because the Democrats had already won the 2010 gubernatorial election.

In 2012, while running for re-election, Martin, Kentucky, Mayor Ruth Robinson and a cabal of co-conspirators targeted residents living in public housing and in properties Robinson owned, threatening to evict them if they did not sign absentee ballots that Robinson and her family had already filled out. Robinson also targeted disabled residents, and offered to buy the votes of others. She was convicted and sentenced to serve 90 months’ imprisonment.
