If they move to Kenya there’s the bonus that they might get elected President of the U.S. some day.
That actually sounds like a good idea for a sign they can post at their border, and airport.
“Welcome to Kenya. Where any little bastard can grow up to be President of the United States.”
... Although that might require them to slip back over, pretend to be a “Constitutional law professor”, suck on a crack pipe for a few years, and spend a couple of years as a rabble rouser and U.S. Senator.
