Horse crap... and full, repetitive horse crap, at that.
Posit the following vote totals, just for the sake of demonstration:
OBAMA: 1,000,000 votes.
MITTENS: 1,000,000 votes.
OTHER: 5 votes.
Further posit that my vote is the sole ballot remaining, and yet to be cast.
Demonstrate: How my not casting a vote for Mittens increases Obama's vote total from 1,000,000 to any other number.
Use both sides of the paper, if necessary. Show ALL of your work.
Not genuinely surprised there's been no answer yet, mind you... but, still.
{^) There'll be all kinds of electoral vote count hooptidoodle in the response, which will appear to have merit, except that it ultimately boils down to the bitter truth: the guy who loses will have lost becaue not enough people voted for him. The loser's side, be it Obama's or Romney's, will squawk that "you didn't vote for my guy so it was the same as voting for the other guy," but ultimately, will boil down to, simply ... their loser didn't get enough votes.
Only need one side of the paper to figure that one out.
Demonstrate: How my not casting a vote for Mittens increases Obama's vote total from 1,000,000 to any other number.
God protect and keep this great nation from the unabashedly craven... and the profoundly innumerate.
