Rules for winning:
Keep out the Kitsch, Internet Humor, Naughty Humor, and Seriousness.
You wanna win, you win by being clever, without being square. The joke on your poster is absolutely retarded - no offense to you, but a lame internet meme with an implied swear does not scream "government" material to me. Don't descend into grade school humor to fuel your campaign. Organize a relevant stance with a good team of PR people on campus and whore the shit out of yourself by giving to the students and positioning yourself as THE guy to vote for.
How you do it is up to you, but remember this isn't middle school.
