You can vote for a character that you admire, or the one you find the most interesting. You can pick the one who would be the best drinking buddy or the one you'd most like to see in a brawl with Starbuck.
I didn't have room to add Col. Tigh, Lt. Gaeta, Billy Keikeya or Tom Zarek. I didn't think they would make the top 5 anyway. If this assumption is not correct, add your support for one of those characters in this thread.
