The "good-enough brain" part is actually understatement. People with President Bush's academic and other accomplishments (dullards don't graduate from Harvard's Business School, can't learn to fly a fighter jet and don't have a net worth of some $16 million earned by themselves) have very high IQ's.
Just some food for thought - Which 20th century presidents had/have the highest IQs?
Bill Clinton and Richard Nixon.
Not meaning to slight the intelligent here, but the author says Bush is intelligent enough, and it clearly bears out in the analysis.
Bush is the millionaire next door sort of guy. Everyone knows he has it but he acts just like the rest of us. He doesnt make us feel small or carry even a whiff of an I am SO much better then you attitude. Your nice middle class son probably could ask his daughter for a date without daddy getting upset.
To put it in a nutshell, he likes us and we return the favor high IQ, big bank account and all. As opposed to those mentioned who have very high IQs (maybe) but give us the impression that they hold us in contempt.
