Reply #16: I have to chuckle at your first comment, considering the point of the OP

"Caucus results are not necessarily reflective of primary results."

It just seems ironic, although I understand your point, sort of.

Hillary won one urban county (we have what I would consider only 2 urban counties -- Clark and Washoe, and at that, neither are what other states might consider truly urban), which is Clark County, where Las Vegas is. http://www.nvdems08.com/

And remember, Edwards was still a factor then, so I don't know how his votes pulled from either Obama or Clinton.

Bottom line is that, to account for the wins in NV, one would have to look at ground games the candidates had in each of these counties -- there's no apparent pattern.

edit to add 'sort of'
