Maybe Trump pardoning Joe Arpaio might mobilize Arizona Hispanics to vote Democrat.
I think also it will depend on the Maricopa County (home to Phoenix) because Trump won it by only 3 percentage points and that if Clinton succeeded to flip it in 2016 (I mean if we shift the 45 546 people margin that voted for Trump in the Maricopa County to Clinton) she might have won Arizona. In fact, that would have given Trump 1,206,855 votes in total in Arizona and given Clinton 1,206,713 votes, thus making Arizona a very very close race.
