McCain has an interesting section on his official website with a playable version of "Space Invaders"
The name is changed to "Pork Invaders" and you play as the McCain spaceship (campaign poster?) and get to shoot Vetoes at Piggy banks.
Obama has no such cool videogames.
This very well could be the deciding issue of the election.
