You’d think. But one of the reasons the already funded wall has not been built is ranchers complaining about their property.

Ironically, you better believe Trump won’t think twice about applying eminent domain to build a wall.
There will ALWAYS be some loony tunes who do not live in reality. Even if they are offered 5 times what their property is worth, they will stubbornly refuse to sell.
But it all depends on the reason for eminent domain execution. If it is for a highway, hospital, airport, or a big mall, then it is one thing. If it is just because the neighbor wants a bigger yard, then it is another thing. Any court should decide. That is why spend Billions on courts.
