There are all of the "Independents" who just like pretending they are independent-minded when in fact they are basically lifelong Democrats or Republicans.
There are all of those idiots who want to vote for the winner (like those who buy a ticket for the favorite in the Kentucky Derby even when the odds are below 1:1) who will vote for Obama or Romney, not because they prefer either, but because they want to say they voted for the winner.
It is truly sad.
There are no polls left in Oregon and much of Washington anymore. All elections are “vote by mail”.
