When we look at what Trump said,
When do we beat Mexico at the border? They're laughing at us, at our stupidity. And now they are beating us economically. They are not our friend, believe me. ... When Mexico sends its people, they're not sending their best. They're not sending you. They're sending people that have lots of problems, and they're bringing those problems with us. They are bringing drugs. They're bringing crime. They're rapists. And some, I assume, are good people."
It is demeaning to Hispanics in general and Mexicans in particular.
I don't think it hurts the GOP much, but it does not help Trump, to insult so many voters.
And yes many Hispanics voters took his words as an insult if not to themselves,
then to their parents or grand parents, who worked hard to build a new life for their family.
If those are his own choice of words, he should be way more selective,
if the words are those of a speech writer, Well Trump already knows those words, "Your Fired"!
