The presidential nomination process is the weakest part of our political system and, not coincidentally, the only one not addressed by the Framers of the Constitution.None of the successive reforms made since 1968 has produced a perfect system, and in a nation of this size none can.A national primary would penalize all but a few nationally known candidates. Caucuses tend to favor candidates with constituencies of well-organized voters. Reasonable people can differ about whether it’s fairer to allocate delegate proportionately or by winner-take-all.Arguments over the rules inspired one of my Rules of Life which is: “All process arguments are insincere, including this one.” A loser’s real gripe is not with the process but the result.
