Cliched as it is, if you aren't a part of the solution, you're a part of the problem. A small part, but size doesn't matter. At least that's what I tell myself every weekend.

So, yes, your vote makes a difference. It counts for one vote. But actually, it can mean a little more than that. If 20 percent of the population votes tomorrow, and say, Carol Moseley-Braun wins by a narrow margin, Peter Fitzgerald loses only the election. But, hey, I could have had the rest of the votes.
