Yeah, I think it's accurate that Trump is a minority President.  By all measurable evaluation tools.

For instance, on things like college aplications, there are ethnicity queries requesting an applicant provide information on their ethnic background by chekcing a box for one of these: "American Indian or Alaska Native", "Asian", "Black or African American", "Native Hawaiian or Other Pacific Islander (a new category)", or "White".

There's no "Orange".  It's so unusual there's no box for it.

Trump is definitely a minority.
