Nevada after 2012 will probably look something like this:
Did you use the new population estimates? I think the Reno district is going to have to extend to Elko or down to Pahrump in order to take in enough residents. Any district that includes the rest of the state will be dominated by Vegas-area suburbs/exurbs like Henderson, Boulder City and (if not put in the Reno district) Pahrump, if not Las Vegas or North Las Vegas itself. About 85% of that district will probably end up being in Clark County no matter what.
