As reality has descended on Trump he has started backed away from the thirty foot wall he promised in the campaign (which defiantly became a forty foot wall when Mexico said they wouldn't pay.) It was also supposed to go six feet underground to prevent tunnels. He was pretty specific, "On the fence -- it's not a fence. It's a wall."
Of course, he later wanted the wall to be see-through so people wouldn't be killed by giant bags of drugs being flung over the wall by catapult. That idea was so outlandish, I didn't believe he actually said it and chalked it up to the usual media bias. But, it's on tape in front of the whole press corp. Parts of the wall need to see through so people don't get hit by bags of drugs. "Because if you get hit with a sixty pound bag of drugs, you're done." Yep, he said that. +facepalm+
After that, I was haunted by the image of an old cowboy riding his horse across the desert when a big bag of drugs comes whistling out of the clear, blue sky and obliterates him.
Trump sold the idea of a cartoon wall to a public that believes the crap they see in late night TV infomercials while the rest of the Republican party cringed. Now they're trying to find something practical angle to spin it. His followers were never chanting, "Build the fence!"
