If you notice they tend to have quite a few key things in common. Typically (but not always) fatherless, drug use, homosexuality, promiscuity, years unaccounted for abroad, sealed records and now we are seeing a pattern of shaky citizenship-which may just be that 30-40 years ago when they began grooming them the country was predominately European heritage and it was more difficult to find these ethnicities. That would fully explain why we are seeing such strong representation with Cubans. 30-40 years ago, Cubans and Puerto Ricans would be who were the more plentiful of the "hispanics".
I know it sounds bizarre but over and over the establishment shoves that type of candidate on us. I have never seen someone able to stand up to them like Trump has. Time will tell how this all works out....hoping for the best!
