If Romney wins the Republican nomination are you going to flip a coin before you vote for a President?

I wish I could vote... My parents are both Republicans, so I'm guessing they will vote for Romney. I support Democrats, (yes, I'm a Liberal) but I don't believe Obama would be the best choice to represent the party. He changes his mind too much and does not effectively stand up for what he believes in. Romney wouldn't be a bad choice, but I don't think I would vote for him.
