The McCain Presidential campaign has made a $5 million ad buy on the Olympics, $1 million more than the Obama campaign.

According to AdAge, the McCain purchase includes network and cable spots. NBC Universal is airing 3,600 hours of Olympics coverage on its broadcast network and cable networks including NBC, CNBC, MSNBC, USA Network, Oxygen and Telemundo.

McCain has money to spend in August. He has to spend down his primary funds before the GOP convention, because he has opted for public financing after the convention.
