Did McCain really vote?

Why was there no coverage of McCain voting? On almost every channel, we watched the Obamas vote (for about 20 minutes) followed immediately by Biden and his mom. Not much later, Palin voted and even came out and said hi to the press. But when it came time for McCain, no one could get a shot of him. All the shots were of the outside of his polling place and basically just showed a bunch of other cameramen scrambling around. Did he do that on purpose? I thought it was the kind of thing candidates loved. What the heck? Now they have a video of him voting but I'm still skeptical.
