"I won't Al Gore you to death"?
"I know how to spell POTATO"?
Not really sure what an effective VP slogan would be. Without your name -- and I'm not asking for it -- you have to go with something generic. To play off current national events:
"Yes they can... but I will."
"[Name] for change, but only a little bit."
Or you could go with honesty:
"I'm actually asking for this demotion."
"Until there's alcohol, there's me."
The following may apply if your school is on an island:
"We'll build a bridge to 21st Street."
"Vote or get off the boat."
Any other suggestions, whether they're helpful or just for our amusement? Help a young person out!
