A two-prong attack:
Stripped down to its components McCain’s message to voters is this: “Don’t forget. He’s definitely black. And he may be a terrorist.” That’s the message. The nuts and bolts is a concerted effort to keep Democrats from voting — through intimidation, by striking new voters from the rolls, which is going to happen to lots of them, clogging polling stations to create delays that keep late day (predominantly) Obama voters from voting altogether. Smears in the air and voter suppression on the ground.
