Obama Campaign Releases New Ad, Targets Dick Cheney's Endorsement of John McCain

If I were John McCain, Dick Cheney would be the last person I would want to endorse me. He is tied to President Bush and he wasn't a good vice president either. He's linked to questionable behavior during his tenure.

The ad opens by touting Obama's recent endorsements from investor Warren Buffett and former Secretary of State Colin Powell, then cuts to video of Cheney from an event Saturday in Wyoming.

"I'm delighted to support John McCain," Cheney says. "I'm pleased that he's chosen a running mate with executive talent, toughness and common sense, our next vice president Sarah Palin."

An announcer says McCain earned Cheney's support by voting with the White House 90 percent of the time. "That's not the change we need," the announcer says.
