On Iowa (and NH) deciding, I think it's obnoxious that the parties allow them to be first every year, but I don't really mind. In particular, I think Iowa is unrepresentative (though not as much as often assumed --
here's a breakdown), but there's something to be said for the candidates introducing themselves in a thorough way. Of course this year ads seem to have decided in large part.
The breakdown is interesting to me, as I have relatives in Iowa who are in agriculture, so I am always surprised at how little of the economy agriculture is.
