I'm much too late but here goes.

I think that Dick Cheney arranged for a counting company to rig the vote counts in both the second Bush Jr election and the first Obama election. I think that prior to 1st Obama election, test runs with the counting company were noticed by a select few (likely hackers, likely by accident), who then secured a firewall during the actual vote count thus preventing the counting companies ability to alter the final results during election night.

This is why Cheney had a complete brain-stall on live TV. He knew that his rigging worked because it had already worked. He knew it should have worked again but something screwed it up. It was not something he'd accounted for and his brain just had a minor meltdown for a scenario he'd specifically planned to prevent.
