I would not put any faith in Caucus state polling, its just too different. If Trump wins, great for him, if he loses, just like IA I can’t say I’d be hugely shocked. Caucus is just too oddball to get a good read on, and you have forces in play that don’t exist in secret ballot voting.
It’s secret voting here. I don’t understand why you think Nevada is Iowa.
The biggest issues here are immigration and economy, plus we have a lot of military. Many tech companies are relocating here.
