coming from someone that doesn't know the full ins and outs of computers, I think the moderator of the site found out that people were deleting their cookies and revoting and deleted all the extra votes based on duplicate IP's. I don't know if they have a way of automatically regulating it based on the IP and not the cookie so the guy with the truck is probably going back to the same old tactic of deleting the cookie. When I checked this morning, the Evo was in the lead by %but pat had more votes and the truck was way behind.
I think at this point Pat's original thoughts are correct that the admin will probably notice the scandal and just close down the voting or something.
