Democratic candidate Terry McAuliffe’s campaign for governor has launched another televised salvo at how Attorney General Ken Cuccinelli’s (R) office has handled a Southwest Virginia gas royalties case.

The McAuliffe camp unveiled a new ad Thursday taking aim at Cuccinelli on the subject, only the latest of several television spots aired by McAuliffe and his allies about the case. The state Inspector General is now investigating the actions of an attorney in Cuccinelli’s office who is alleged to have given improper legal help to out-of-state energy companies who are being sued by landowners over royalties from gas extracted from their land.

The latest ad features a clip of Cuccinelli saying: “Southwest Virginia has never had anybody fight harder for them than I have.”

Then the announcer says, “But now dozens of new e-mails have been uncovered that show Ken Cuccinelli’s office helping an out-of-state energy company rip off Southwest Virginia landowners. The same energy company that’s funneled over $100,000 to Cuccinelli’s campaign. Ken Cuccinelli. He’s really not for us.”

Cuccinelli spokeswoman Anna Nix responded that “Terry continues to do what’s best for Terry” while her boss seeks to help the state.

“Terry McAuliffe, who refuses to stand up to his Washington friends to protect our energy industry and who was recently exposed for being incapable of talking in detail about important policy matters, has no choice but to lob misleading attacks to try and distract voters from his unserious campaign,” Nix said.
