good explanation.
The US didn't make nuclear weapons in the 1940s by going for Third World foreigners: we snarfed up the Nobel Prize winners, back when that meant something.
We didn't send a man to the moon in the 1960s by importing a bunch of barely-English-speaking pagans who were in it only for a green card, but by relying on Patriotic Feeling. One of the few things JFK did right, besides Taxes.
Also I trust we can agree on the following: any current GOP candidate over Hillary.
