I read just the excerpt.
Substitute Obama for Trump there and the writer nails it.
The writer obviously has no understanding of real Americans.
Most candidates seek to define themselves by their policies and platforms. What differentiates Trump is not what he says, or how he says it, but why he says it. The unifying thread running through his seemingly incoherent policies, what defines him as a candidate and forms the essence of his appeal, is that he seeks to speak for America. He speaks, that is, not for America as an abstraction but for real, living Americans and for their interests as distinct from those of people in other places. He does not apologize for having interests as an American, and he does not apologize for demanding that the American government vigorously prosecute those interests.Would that have made a difference to you?
What Trump offers is permission to conceive of an American interest as a national interest separate from the international community and permission to wish to see that interest triumph. What makes him popular on immigration is not how extreme his policies are, but the emphasis he puts on the interests of Americans rather than everyone else. His slogan is Make America Great Again, and he is not ashamed of the fact that this means making it better than other places, perhaps even at their expense.
