I'm from Missouri so all I can say about Nevada with any real knowledge is that that I don't understand Nevada. I was sure the state would not go to Obama in the General Election, it did. I was sure Harry Reid would lose, he didn't.
I know that Nevada has lots of desert and mountains, lots of gambling and lots of prostitution. Beyond that I'm only sure of what I don't know.
at least this an encouraging sign.
Nevada has changed over the years. It used to be that you had a fairly liberal Northwest Nevada (Washoe County), a very conservative (but sparsely populated) rural area, and a fairly conservative Southern Nevada (Clark County).
That has all changed, and you have a more moderate Washoe County, and a much more liberal Clark County. And a much bigger population, further diluting the influence of the rural areas.
It is a huge public union state and many make their money by getting state contracts including republicans.
