OK, I’ll type slow for you:
Two people are running for an office. There are 4 people in the electorate.
Persons 1-2 vote for Candidate o. Person 3 votes for candidate R. Person 4 writes in “Sarah Palin.”
Who wins the election? What is the result of Person 4’s tantrum vote?
Simple arithmetic.
obama thanks you and yours for the vote for him. You can play word games until the cows come home, but a tantrum “I’ll just eat worms” vote is THE SAME AS a vote for obama (there, I tightened up that little word game you have played on so many responses here).
We have exactly 2 choices: obama or Romney. There is no 3rd option. If you do not vote for Romney, you increase the % of votes going to obama.
Period.
Wrong again. We have (unless there's a miracle, and they do happen) exactly 1 of 2 outcomes: Obama or Romney.
We have many choices, including the choice to reject both of them and vote third party -- if one in three Americans do that, the winner will get in on such a putrid plurality that he will go into office and face the nation and the world with it on record that nearly two of every three American voters rejected him.
Your arithmetic is screwy.
