I’m already devouring Brian Doherty’s Ron Paul’s Revolution.  Brian’s such a great writer and such a careful historian – a true treasure.  To me, though, the biggest puzzle isn’t how Ron Paul can command the loyalty of 5% of the U.S. population, but how Paul manages to repeatedly win re-election in a seemingly normal congressional district.

The Median Voter Theorem usually works pretty well in the real world.  Why does it fail so badly for Ron Paul?  Please show your work.
