(CNN)–With only four days before election day, Sen. John McCain is ending the battle of the airwaves with a pair of 30-second spots.
"Obama Praising McCain" echoes a Web ad released a month ago: “Praising McCain." That spot spot shows prominent Democrats commending the Arizona senator for his stances on public policy and his leadership abilities within Congress. "Even Obama has Praise for the Maverick," read the screen.
In the new 30-second spot, an announcer begins “The truth on global warming”: the only other speaker in the ad is Obama himself. "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," says Obama. "I want to thank Senator Lieberman, as well as Senator McCain, for the outstanding leadership that they've shown.”
The second spot, “Freedom,” brings the focus back to McCain’s biography. “I've served my country since I was 17 years old, and spent five years longing for her shores,” says McCain, evoking his time as a prisoner of war in Vietnam.
“I came home dedicated to a cause greater than my own. We can grow our economy. We will cut government waste,” he says, adding — in an apparent subtle swipe at Barack Obama - “Don't hope for a stronger America. Vote for one. Join me.”
The campaign said the ad will air in key states. On a Friday conference call, campaign manager Rick Davis said he expected McCain to out-spend Obama on the air in the race’s closing days.
