One camp thinks a US president helped orchestrate the murder of 3,000 Americans in conjunction with al-Qaeda and the other wants to see definitive proof of someone’s citizenship. The differences couldn’t be more profound.

(Politico) — I’ve been looking for a good analogue to the willingness of Republicans to believe, or say they believe, that Obama was born abroad, and one relevant number is the share of Democrats willing to believe, as they say, that “Bush knew.”

There aren’t a lot of great public numbers on the partisan breakdown of adherents to that conspiracy theory, but the University of Ohio yesterday shared with us the crosstabs of a 2006 poll they did with Scripps Howard that’s useful in that regard.

“How likely is it that people in the federal government either assisted in the 9/11 attacks or took no action to stop the attacks because they wanted the United States to go to war in the Middle East?” the poll asked.

A full 22.6% of Democrats said it was “very likely.” Another 28.2% called it “somewhat likely.”

That is: More than half of Democrats, according to a neutral survey, said they believed Bush was complicit in the 9/11 terror attacks.
