There were LOTS of discoveries of WMD throughout the campaign, along with mass graves and other sundry depravities. The media simply flat-out refused to cover them. Remember, back then the media still hated GWB because he had "stolen" the election from their shining hero, the mess that is Al Gore.
They were beside themselves when George Bush "showboated" climbing up that rubble with a megaphone and announcing we would make the murderous Islamic terrorists pay; they were apoplectic when he heroically deplaned on that carrier to speak to the crew (to this day they deride him for the "MISSION ACCOMPLISHED" banner behind him when he made that speech. That banner was acknowledging the CARRIER's completed mission, not the war. In his very speech there he said there was MUCH more to be done).
There was a VERY real sense in the 2001-2004 era that the Democrats were finished because of the national fervor and this brave Republican president. What the Democrats have done then and since is try to denigrate American patriotism, American might, and anything else that (correctly) shows them as hostile to the glory of this country.
I am quite convinced that 2014 is their Waterloo, and they know it. People have simply had enough of these '60s and '70s "activists" now in power, and the young, black (always with the stereotypes, the Leftists) "President" they propped up to represent their aims.
Quickly rising into power are the men and women who came to fruition in the Reagan era -- Ted Cruz, for a major example -- and their disdain for these old, antiquated "activists" still trying to hold on while the world passes them by is palpable. I think Americans are finally ready to move on, finally leaving behind that pretty much useless generation that can't acknowledge that this nation has made heroic strides since Selma, and Kent State, and Woodstock.
I expect the administration to freak out and pull a Venezuela at some point in the near future.
