AZ has had a lot of new registrations. Would those voters be included in this poll?
It's the new registrations in September and October that can make a travesty of conventional wisdom.
Arizona could have a nasty surprise awaiting Donald Trump. There has never been much enmity between the masses of Anglo and Hispanic voters. Older white Anglo voters often have some Mexican-American in-law, and this person could influence some white Anglo votes. Assimilation into the American way of life does not require that one abandon interest in the well-being of people of one's origins.
