This whole thing is a popularity contest, but run for Sec. I guess. What is your popularity? What is your height- and why is important?
The height's unimportant -- it's just a bit of a running joke that the shortest candidate always wins, since that's what happened last year. I'm moderately popular, perhaps a little better than average, but my problem is that in every contest the sort of people who would vote for me have a candidate they would rather vote for -- Candidate #1, Candidate #3, and the incumbents. I personally am friendly with both incumbents and Candidate #3 but not Candidate #1, who I've never gotten along with, which is one of the reasons I'm leaning towards running for President -- even if I don't win, I may split the vote and get the incumbent President reelected.
Surely such things are unimportant in this context? Or are you expecting a patronage position? I say go with what you want, but again how seriously is this all taken. In some places the StuCo actually has a fair degree of power and importance. In others, like mine, it takes an advisory and organizational role in student affairs alone.
