Presumably those Hispanics in Nevada are American citizens, in order to vote, owe their first allegiance to America, not Mexico.
And they hear the call of Trump, that continued illegal immigration is dangerous, in view of horrific instances of crimes, failure to deport, sanctuary cities, etc.
People like those Hispanics have been my fellow citizens, fellow service members, all of my life.
One of my earliest members was from around age six, in Colorado, where the water truck driver who watered our gravel street, convinced me he was the Cisco Kid.
