Well, Mr. McCain ought to know about that subject. What with all the sneering comments he made and juvenile snickering he did in the debate before NH, he knows full well what it means to be a major league jerk. He's been known for that side of his temperament for years.
Besides, the margin in MI, last I checked, was hovering around 9-10%. Mr. McCain doesn't take defeat well so, I'm not surprised that this story is circulating. Who knows if its even true? Regardless, its definitely sour grapes.
Statewide margin.
However, much of Gov. Romney's support was lumped in Detroit, and with by-district delegate assignment, Sen. McCain gets almost the same number of delegates as Gov. Romney. :-(
