We actually used mind-control. Democrats went to the polls and unconsciously cast their vote for Bush. Got the idea from the Spongebob Movie.
Shhhh. Don't tell them they can avoid the mind control by smearing themselves with petroleum jelly and making a hat out of heavy duty aluminum foil.
Some guy in New Jersey went too far the other day and coated his entire hotel room in petroleum jelly. On the other hand, he might have been hosting a caucus or precinct meeting.
