Yeah, Nevada is gone for the Republicans. They are tied with Minnesota for the worst state party organization, while the Democrats have a machine to get out their voters. Also the demographic trends aren't good for the Republicans either.
True the demographic trends aren't great but the Dems haven't had a governor elected from their party elected there in several years even though the State Legislature is run by Democrats. The R's still have 2 of the 4 US House Seats. They have a US Senate Seat and the governorship.
