Obama Ad: McCain And Palin Are No Mavericks

The Obama campaign has released a new ad responding to the McCain/Palin spot out earlier today labeling the Republican pair "Original Mavericks."

The spot, "No Maverick," will air "in key battleground states across the country beginning today," according to the campaign. No word on how often the campaign plans to run the spot or what exactly the "key battleground states" in question are.

"They call themselves mavericks," an announcer says in the ad. "Whoa. The truth is they're anything but."

"John McCain is hardly a maverick when 7 of his top campaign advisors are Washington lobbyists," the announcer says. "He's no maverick when he votes with Bush 90 percent of the time."

The spot then takes aim at McCain's new running mate.

"And Sarah Palin's no maverick either," the announcer says. "She was for the bridge to nowhere before she was against it. Politicians lying about their records? You don't call that maverick. You call it more of the same. "
