Come again? Whenever it's close, the incumbent usually gets the shaft, as the undecideds go the challenger's way. Romney doesn't have to win by 5. If Romney gets over 50%, the odds of him winning the EC are greatly on his side.
I'm saying that as the incumbent, as election is being counted in spain by george soros' company (michael savage did a great piece on this)....
If it is very close, Obama will FIND a way to take it.
If we know at 8 pm EST that Romney has commanding exit poll leads in OH, FL, and PENN.... then obama can't steal shit.
