Trump could win Nevada and Arizona and New Mexico and California and Idaho and Montana even maybe Washington state. Not because everyone’s republican but because Hillary is so strongly disliked by Most D voters. I figure at least half of them could vote for trump if he campaigns well for them. Just like when Reagan ran — a charismatic R candidate ( now that’s been awhile, ha!) and an intensely resented or hated D (if Hillary is able to buy the D nomination). This doesn’t mean all these voters will forever remain in the R column, it’s not every election when the D’s nominate such a weak candidate as Hillary ( if they do — a tremendous gift !(
NV, AZ, ID and MT are solid Trump.
The Left Coast states of WA, OR and CA are a lost cause - no Republican will carry them.
NM is a possible toss-up but at the moment leans D.
