Love your analogy ... and I think you’re right. Unfortunately, the Repubs don’t have the balls to go through the breach in the wall. They’d rather stand back and whine/complain & snivel about what Trump is saying & worry about what names the Enemedia will call them if they agree with him. Total misread by Repubs of a good chunk of the American public - Trump is getting traction because he is saying “the things that must not be said” (but are TRUE) in the interest of the Left’s version of Political Correctness ‘reality’.
That wall not only has been breached, but oppened up. The beginning of the end of “PC” nonsense.
