Earlier, I noted that 76 percent of Nevada voters who are registered Democrats live in Clark County, home to Las Vegas. But according to the preliminary entrance poll, 68 percent of caucusgoers came from Clark County, so perhaps fewer than you might expect given registration numbers. The preliminary entrance poll found that another 21 percent came from Washoe County (home to Reno) while the remaining 10 percent came from other parts of the state.
