With the primary season more and more agreed to be over with.... I still think its interesting nobody ever asks much why the US alone has such a strange primary system. It's a question we used to ask ourselves according to this piece from the archives of the New York Times "Direct Primary in Operation: So far is has failed ot meet expectation
", by Professor Henry Jones Ford of Princeton University, April 19, 1909. I wonder if even the Obama campaign would agree to some degree at this point.
Note that the Crawford County system it talks about is all a Pennsylvania story. For more see: The Origin of the Direct Primary: The Crawford County System
