I doubt if anyone knows how it will end. Including Donald Trump.
Previously, he didn’t seem to care if they called it a wall or even something silly like “peaches“. Now he is back to insisting that everyone call it a wall again and “stop playing political games”, even though it is obvious that the person who keeps changing the name is Trump himself.
Regardless of what you call it, a wall is a completely stupid idea, and no matter how much Trump lies about the need for one, it is obvious that the only thing a wall will do is help Trump with his most rabid base.
