If they are intelligent then the xenophobia and desire for authoritarian government to push policies that would be difficult to pass is what they rationally voted for. For well off intelligent racists who might get along with some minorities but see them as exceptions as opposed to the norm Trump is doing a good job.

Got to not see it through the eyes of someone who is concerned about the economy, health care, or international relations. But, bigots who have a long term idea of the America they want and willing to suffer economically for what they believe is a better future for their kind.

And those who are intelligent are good at arguing they aren't racist, which is why they are smart enough to come up with slogans like America first as opposed to ethnic cleansing and use of minorities in some positions to point as examples of how they are totally not racist.
