There’s something that genuinely puzzles me. Why do so many Democrats seem to demand that their presidents in particular be geniuses? That’s certainly not my view but I have a peculiarly jaundiced opinion of politicians. My dad was very involved politically, his uncle was sheriff of St. Louis, his grandfather was a party bigwig, the chairman of the St. Louis Board of Aldermen was a close family friend, I went to school and Boy Scouts with Symingtons and Schlaflys, etc..
I don’t believe that Barack Obama, Bill Clinton, or, (heavens help us) Hillary Clinton are great minds. I think they’re politically astute but otherwise perfectly commonplace members of the professional class. I.e. IQs one or two standard deviations above normal; smart enough but no geniuses. I’ve known truly brilliant intellects over the years. They ain’t it.
I don’t expect presidents to be super-intelligent but I do expect them to be hard-working and not to have just fallen off the turnip truck. In that I’ve been gravely disappointed in recent years.
