I always thought of Celes as the main character. She gets to gather the party in the world of ruins. It's not just the part with her on the island, I thought. Her theme tune is very prominent throughout the game, she gets to have the romantic love-story, and a lot of character development that is typical of RPG protagonists, like originally fighting for the wrong side, getting wrongly accused, etc.
However, I was tempted to vote for Lord Chainsaw's ass...
