SO...Little Lindsey is RIGHT. According to NYT, the "wall" IS a metaphor. cooked up in 2014.

As Mr. Trump began exploring a presidential run in 2014, his political advisers landed on the idea of a border wall as a mnemonic device of sorts, a way to make sure their candidate — who hated reading from a script but loved boasting about himself and his talents as a builder — would remember to talk about getting tough on immigration, which was to be a signature issue in his nascent campaign.

“How do we get him to continue to talk about immigration?” Sam Nunberg, one of Mr. Trump’s early political advisers, recalled telling Roger J. Stone Jr., another adviser. “We’re going to get him to talk about he’s going to build a wall.”

Talk Mr. Trump did, and the line drew rapturous cheers from conservative audiences, thrilling the candidate and soon becoming a staple of campaign speeches. Chants of “Build the wall!” echoed through arenas throughout the country.

Now, Mr. Trump’s fixation with a border wall — the material embodiment of his keep-them-out immigration agenda — has run headlong into the new realities of divided government, pitting him against Democrats who reject the idea out of hand. The impasse is particularly remarkable given that even some immigration hard-liners do not regard the wall as their highest priority and fear that Mr. Trump’s preoccupation with it will prompt him to cut a deal that trades a relatively ineffectual measure for major concessions on immigration.

1. And this wall will collapse on the repugs and bury them ... a stupid, ineffective, and pathetic...

attempt (wrongly directed) to slow illegal migration. It won't work as all of us know, history is full of broken walls.
