An interesting read, although I think he has a bit of a chip on his shoulder.
The press and his opponents highlighted President Bush’s occasional stumbles when giving a speech. President Obama’s similar verbal miscues are ignored.
Oh nonsense, I could reel off a list of Obama gaffes from the present to back before he became President, largely because people who oppose the President repeat them endlessly. Those same people seem to think Obama's the first President ever to use a teleprompter, or at least are pretend they do.
Now, I never thought Bush was unintelligent; he ran his father's election campaigns, and you don't get to be governor of a large state, or President, without any smarts. I do think that Bush and many of his administration suffered from some alarming cognitive biases, and the smarter a person is the easier it is for them to fall into the trap of believing in their own inevitable correctness (I've done so myself many a time). I can't help feeling that he's treating the financial crisis and some structural deficit issues as unforeseeable events that just happened to fall out of the sky during the tenure of the Bush administration.
I suppose what I'm saying is that I consider Bush's tactical intelligence to be a lot higher than his strategic intelligence; he's a very skilled politician but a pretty poor show as a statesman. History may prove me wrong but I'd be willing to put a bet that it won't.
