I read a story in a santa fe newspaper (can't find the link any more) about what a disaster the NM caucus was. apparently, the national democrat party ran the whole show, and made a hash of the entire thing. they changed/consolidated caucus locations, disallowed crossover voting, and in general just overruled the locals and the way the things had been run for years.
I think it had more to do with giving NM governor bill richardson an early caucus victory than anything else. at least, that was the theory.
