Because the election is over and it doesn't matter?
But it does matter. The bigger Bush wins, the harder it is for the media to start saying that has still lacks a real mandate. Believe me, they will be saying that in about a week.
It does matter, because reporters like Wendell Goler are out there spouting off about how Bush once again one with "the slimmest of margins", being only four points over the necessary 270 EV's to win (Wendell apparently forgot that New Mexico and Iowa are in the union, and that both together put Bush SIXTEEN points over, not just four). The more EV's we've got in our column over 270, the less reporters can claim that the President doesn't have a mandate, or that he only squeaked by, etc.
