Mark Steyn, as only Mark Steyn can, hoists JFK with his own petard. Money quote:

Primary season gives the party's electorate a chance to rattle the leading candidate and make him a better campaigner. This time round the leading candidates - Dean, Clark - rattled the electorate and in their stampede to the fire exits they wound up sweeping the quintessential "None of the Above" man to victory. They made a very basic miscalculation: Howard Dean was a dull centrist governor pretending to be nuts, John Kerry is a nut passing himself off as a dull centrist.
