Local and national Democrats have spent days now accusing Alvin Greene of being a Republican plant. Some have even called for a federal investigation, with his former opponent bringing in a team of his own to review the election results.

(Greene, who won the Democratic nomination for U.S. Senate — South Carolina, is an unemployed veteran with an interesting history of felony obscenity and a failure to file proper election documents. Many expected his opponent, Vic Rawls, to win by a large margin.)

But Tom Jensen of PPP, a left-wing polling firm, says the result wasn’t totally unexpected. He explains:

A polling information center has concluded the surprise primary victory for Alvin Greene was not a GOP plot, but a completely random outcome based on an election in which both candidates were unknown.

“I don’t see any evidence of GOP chicanery,” said Tom Jensen, the director of Public Policy Polling .

Rep. Jim Clyburn has called for an investigation into Greene’s win, saying he has seen evidence of tampering in a number of races across the state. Jensen disagrees.

“Ultimately, what we’re concluding is it was pretty much completely random who was going to win given that no voters had heard of either of the candidates,” he said.

Interesting.
