"Is this office important per say?" just kidding
try these:
annoy anyone you see and tell them you'll stop bugging them if they vote for you.
"if you can read this sign, you are smart enough to vote for me"
"VotE 4 mii 4 7th gr8d ofFis andz I give u a cAr" (get it, I wrote that in text message form)
"my campaign is running out of ideas to put on this sign, so here it is"
