Just another opinion worth about as much as you're paying for it, so here goes. I think a large part of the resistance to "Trump's" wall is the dipshit way he's gone about it. It was going to stretch continuously from the CA coast on the Pacific to the Texas coast on the Caribbean, be 30' tall - the very best, Mother of all Walls, and most importantly, Mexico is going to pay for it. If instead he approached the subject with, "Look, we should improve and expand the Mexican border walls and fencing at strategic locations, where the existing walls at Nogales, El Paso, and San Diego are't satisfactory . . ." I think he would have gotten complete buy in from Republicans and a lot of Democrats. (Some Democrats would oppose any Trump initiative, just as all Republicans opposed any Obama initiative.) The biggest problems with Trump's pitch is that he back tracked on the funding source. This is enormous, because the coast to coast proposition that he proposed would cost at least $125 billion, and possibly closer to $500 billion, which is a tad more than pocket change, even for the federal budget. The $5.7 billion ask isn't even a respectable down payment; it's just symbolic fodder for the low information Trump base, making it especially easy to oppose.

Now that Trump has showcased his wall as the hallmark of his administration, I doubt he can get any Democratic buy in for even a reasonable proposal, let alone his Mother of all Walls. Trump fvcked himself on this. He owns it.
