If the media is a hard nut to crack on a matter on which the public is indifferent...
How much harder will it be for Democrats who are foolish enough to oppose the war in Iraq, in the face of the full force and fury of American vengeance?
No way the media lobbies against that war, they know who spreads the butter on their ratings bread.
I think if Bush had vetoed CFR and made a strong public case about why he did so, he'd have beaten override (did it even pass with 67 votes?). And that's as good as a win, so that makes him more difficult to oppose on a war in Iraq, not less.
It is a win only for his term in office. The veto power is not absolute. The only way to actually kill it is to have it found unconstitutional.
