I can’t find much info on polling re: 9/11 conspiracy theories but I guess it was more prevalent than I realized:
Democrats in America are evenly divided on the question of whether George W. Bush knew about the 9/11 terrorist attacks in advance. Thirty-five percent (35%) of Democrats believe he did know, 39% say he did not know, and 26% are not sure.
Republicans reject that view and, by a 7-to-1 margin, say the President did not know in advance about the attacks. Among those not affiliated with either major party, 18% believe the President knew and 57% take the opposite view.
Overall, 22% of all voters believe the President knew about the attacks in advance. A slightly larger number, 29%, believe the CIA knew about the attacks in advance. White Americans are less likely than others to believe that either the President or the CIA knew about the attacks in advance. Young Americans are more likely than their elders to believe the President or the CIA knew about the attacks in advance.
Rasmussen tends to slant right but those are pretty considerable numbers. It’s not clear whether the positive/unsure respondents were ‘lihops’ or ‘mihops’ – let it happen on purpose vs. made it happen on purpose – as obviously not everyone who thinks Bush knew about 9/11 in advance necessarily thinks he also planned it. And mistrust of the official explanation is/was not exactly a fringe position:
– Many adults in the United States believe the current federal government has not been completely forthcoming on the issue of the 9/11 terrorist attacks, according to a poll by the New York Times and CBS News. 53 per cent of respondents think the Bush administration is hiding something, and 28 per cent believe it is lying.
Only 16 per cent of respondents say the government headed by U.S. president George W. Bush is telling the truth on what it knew prior to the terrorist attacks, down five points since May 2002.
-There are probably more Truthers than I realized
-There are definitely more Birthers than I realized
-The Birthers are farther from mainstream opinion than the Truthers were, though obviously the issue of 9/11 is a lot more complicated than the birth certificate stuff. The Bush-9/11 poll was taken in 2007, so it’ll be interesting to see where belief in the birther conspiracy goes as BO’s popularity changes over the course of his presidency as well.
-The birthers skew heavily toward Republicans concentrated in the South and the remaining elected members of the Republican party are concentrated in the South. I think it’s fair to say the Birthers have more political influence at the moment than the Truthers have at any point.
