About this time in every presidential election, some prominent journalist writes pretty much the same article about how the Iowa Caucuses are a sham masquerading as a real primary, and how the outcome doesn't even begin to reflect what Iowans think, let alone any significant block of voters in this nation. This year, Christopher Hitchens takes a stab at that article. No one, insofar as I can tell, disputes his thesis or the facts supporting it. But no one does anything to change the set-up, either.
