You cannot count on everyone picking the best choice, because the best choice is a matter of opinion and people are always divided (not to mention special interests). Let me ask you a question, if you had to pick one of the other, would you rather be lightly hit on the shoulder, or punched full force in the face by Kimbo? Obviously you would pick the lesser of two evils. It is basic damage control. :P You are not helping cut down on the damage though when you vote for someone who has no chance.
