Steven Landsburg ranks the eloquence of Republicans in the debate.
Does anybody notice that the best speakers tend to be the least ideologically complex and intellectually nuanced? Huntsman and Pawlenty have real opinions, whereas Santorum and Cain are close to ideological standins. The simpler the message, the easier to communicate... but is simplicity of message really a quality to look for in a politician?
As a disclaimer, I'm a big Huntsman fan, personally, and I'm not a big Palin or Santorum fan. I like candidates both near the top and at the bottom of that list. But I'm not sure this is a good thing to be voting based on.
