This is one of the things that I despise about Trump. Kelo was a bad decision, and is bad law.
Given how much of the land along the Mexican border is privately owned, Trump is going to have to use a lot of eminent domain to get his border wall built.
BUT! BUT! BUT! The land you worked 60-80 hours a week for 50 years would make a beautiful golf course and Trump deserves your property so he can make more money and besides Trumps a billionaire so he knows better than you what to do with your property.
