A slim political victory it was not. Clinton didn't even get 50% of the vote either time he ran for president.
It was really far from slim. Even democrats like Newsweek's Evan Thomas have noted that the MSM simply handed Kerry 15% of the vote:
What that means is that the dem hardcore is now no more than about 30%; Kerry got the 30% dem core vote and another fifteen percent (gullible) kicked in by the media. I mean, for the last year and a half prior to the election every time I turned on the radio or TV or picked up a magazine in a dentist's office, there it was:
"Oh GOD, that George W. Bush is a FOOL, and we're all gonna die on account of what a FOOL that George W. Bush is, oh woe.........
Basically, on a level playing field, i.e. with an impartial media, Bush would have won this election 70/30.
