Well the US Elections aren't decided on popular vote.
If McCain wins Ohio and Colorado he wins.
If Obama wins Ohio he wins.
If Obama takes Colorado, New Mexico but loses Ohio and NH. Its a tie.
Obama wins if he takes NH and Colorado.
Those are the states that matter, everything else is an after thought unless you want to throw Virginia in the mix. At the moment Obama and McCain are tied there. Obama wins Virginia he can lose Colorado and still win.
There's your election in a nutshell. Just turn in now on Nov. 4 and just pay attention to those states. NH, Colo, Ohio, Virginia.
