Keith,
Hugh Fitzgerald has a distinctive writing style (I'll refrain from characterizing it, letting you judge it for yourself), an example of which is here, wherein he refers to J. S. Mill, Michael Oakeshott, Karl Popper, and John Rawls.
A phrase that jumped out at me was "the hectic vacancy of his job": the busyness that keeps an officeholder from actually studying while in office. "So here's all one asks at this point of Barack Obama. Read more, study more. Start, if you will, with John Quincy Adams."
