He understanRAB that shouting and labelling people things usually wins a debate. I wouldn't say he was a man of staggering intellect though, even when compared with Bush.
There's a spoof news report that describes a study done by "The Lovenstein Institute" in Scranton, Pennsylvania, where Bill Clinton is said to have an IQ of about 180, and George W. about 90. In truth there's no confirmation anywhere on what Bush's IQ actually is, but that same "study" said that Kennedy had an IQ of 176, when infact it was closer to 120. The whole report was a joke taken far too seriously, most notably in this country by The Guardian, which later posted a retraction.
George W. Bush did apparently get an SAT score of 1206. That put Bush in the top 16 percent of prospective college students. Al Gore got 1355.
The average IQ is about 105 for high school graduates, 115 for college graduates and 125 for people with advanced professional degrees. With his MBA from Harvard Business School, it's not unreasonable to assume that Bush's IQ surpasses the 115 of the average bachelor's-degree-only college graduate.
It doesn't really mean much, but Michael Moore only briefly attended the University of Michigan at Flint before leaving school.
He's ignorant, and certainly not a great speaker, but I think some people underestimate him ever so slightly. Never underestimate your enemy remember. Especially when he's surrounded by people who are clearly highly intelligent.
