Shouldn't he have to die first? Naming places after living people is a terrible idea, what happens if he gets charged with rape/fraud/assault/tax evasion/election manipulation? We might think less of him...
George Bush International was named after President Bush during his lifetime; Harry Reid International was renamed while the former senator was still alive. It isn't that much of a stretch to name an airport after Trump while that piece of shit is still alive.
However, I would think that Palm Beach would be a better airport to get his name due to Mar-a-Lago.
