Here's the content of Lieberman's radio ad via the Courant:

Facing a challenge from the Democratic left, the first commercial of Sen. Joseph I. Lieberman's re-election campaign casts him as a fighter of "big-oil Republicans."

Lieberman began airing a radio commercial Tuesday addressed to environmentalists, an important voting bloc in a Democratic primary.

Patty Pendergast, an environmentalist, talks in the commercial about Lieberman's opposition to drilling for oil in the Arctic National Wildlife Refuge.

"The Republicans, all they want to do is drill oil and they don't see the ecosystem consequences," Pendergast said. "Joe Lieberman had no problem standing up to the big-oil Republicans. He was the leader on the arctic refuge."

Joe Lieberman voted for George Bush's energy bill, which provided huge tax cuts to the same oil companies now reaping obscene billions in profits on the backs of consumers.

Joe Lieberman's ninth largest campaign contributor this cycle is an energy company that California's attorney general has called "Enron's twin brother" and is being sued for $2 billion for ripping off California's consumers.

Joe Lieberman came out against the Broadwater LNG proposal months after almost every other politician in the region from either party, and convieniently, right after Lamont's challenge began to look like it was for real.

He votes for a damaging Republican energy policy that benefits Big Oil.

He takes over $40,000 and a private flight from a company that makes their profits ripping off energy consumers.

He's wishy-washy on preserving Connecticut's envirnonment when other politicans from both parties aren't.

Joe is the "Big Oil Republican."
