"Dumb" is so subjective

Percentage of Bush supporters/Kerry supporters who believe:

Iraq possessed prohibited weapons or had a major WMD program...72/26
Iraq gave al Qaeda "substantial support" or direct involvement in 9/11...75/30
the majority of people in the world oppose the U.S.-led war in Iraq...31/74

(furthermore, how can over 15 million Kerry voters be so dumb?)

Even if you retreat to the existential excuse of "how can we ever know?", then base it on common sense credibility; the bipartisan 9/11 committee, Senate Intelligence Committee, US weapons inspector David Kay, and DCI special advisor Charles Duelfer all contradict the Bush administration. Not to mention Bush's own flip-flop from WMD/al Qaeda to Saddam-in-jail/"democracy" as main focus of Iraq war.
