At this late date, with the revelation of the 550 tons of yellowcake uranium that Saddam had in Iraq, it is absolutely impossible to defend the mantra "Bush lied". That mantra was about WMDs. The 550 tons of yellowcake, shows that Joe Wilson lied when he published his op-ed piece about Iraq seeking uranium. (Perhaps they were no longer seeking it when old Joe was in Niger because they already had it.)
The bottom line of this is that Bush did not lie about WMDs. Regardless of whether or not one regards that as a valid reason for going to war with Iraq, it must be admitted that Bush was correct about Saddam having WMD programs. Bush did not lie. In fact is was the Dem's who were lying when they claimed Bush lied. They made those statements based on assumed facts. Bush had the real facts.
Of course, most Dems operate in a fantasy world where facts don't matter. In fact, I would contend that most of them don't believe that there is such a thing as an objective fact. I would like to drop one more fact on the Dems. Because of all the anti-war bovine excrement the Dems have been churning out, the war has dragged on far longer than it should have. I'll go so far as to suggest that without their lies, the surge might not have been needed. So the Democrats lied, and people continue to die.
