High school elections advice?

i'm running for cl delegate (sort of like prez) and i need a campain! i just learned this yesterday and i need to have everything ready by monday... any ideas about posters?? i can have 28 normal sized papers, two large posters and i don't know about pens or things like that... and, i don't think i do a speech or anything... Also, i need a slogan. my name's liberty, so i suppose i could think of something with that, but all's i can think of is "vote for freedom. vote for liberty." BUT, what do these elections have to do with freedom?? help!!
