No one's campaigned in Nevada yet, but so far it looks like Richardson has yet to display any regional appeal here. It's tough enough to accurately identify caucus goers in Iowa, a larger state with top significance - Nevada caucus polling should probably be taken with a grain of salt. I have no other recent poll for this state to compare with.
Note that Nevada still has a mucher higher proportion of undecideds than Iowa. So far, though, Hillary is the one to beat in Nevada by more than 3 to 1 over any other challenger. Out of the 4 states polled by ARG in this batch, this is Edwards' worst performance and Kerry's best. It's also Clark's best, which isn't saying much. Obama places second, but has a lot of work cut out for him here. Vilsack is not credible outside Iowa.
