@realjohnboy,
On popular votes, here's some calculations.
There are 207,643,594 registered voters in the US.
If Romney will win 47.2% of the votes, it equals around 98,007,700 votes
If Obama will win 51.3% of the votes, it equals around 106,521,100 votes.
A difference of 8,513,000 votes. But, most of us understand it's not as clear cut as those numbers would suggest.
