New McCain Ad: Obama Once Praised Me!

Emptying out the opposition-research closet, the McCain campaign is up with a new ad featuring one Sen. Barack Obama praising John McCain's approach to global warming.

The spot, titled "Obama Praising McCain," will air in "key states." But it is unlikely to move the dials much, if at all. Obama has occasionally lauded his opponent for his stance on global warming during the general election -- as evidence of past ideological independence -- so the footage shouldn't cause much of a political shock.

Either way, with four days until voter hit the polls, its time for campaigns to utilize all the tolls they have at their disposal. So don't be surprised if we see more committee hearing video going forward.

Here is the script:

NARRATOR: The truth on global warming:

BARACK OBAMA: The right approach begins with the proposal put forward by Senator Lieberman and Senator McCain.

The Lieberman-McCain bill establishes limits for greenhouse gas emissions. It's a framework that's not only good for the environment, it's also good for business.

I want to thank Senator Lieberman, as well as Senator McCain, for the outstanding leadership that they've shown.
