If your intuitions tell you a wall will accomplish anything, your intuitions are terrible at their job and should be fired immediately.
There are way better and more cost-effective ways to approach it. But you guys love the wall not so much because it would work, but because you know you're not likely to get it. So, you can use it to put on a show of being Big Patriots, and then put it to the secondary use of lying about what "liberals" supposedly think about illegal immigration (most recently, claims that liberals want "open borders").
I mean, I hate to break it to you, but things like ladders, ropes, tunnels, humans trafficked in trucks, and boats are not liberal conspiracies. They really do exist, and they really do work quite well against a dreaded wall. The only way a wall could work is to keep it constantly staffed and monitored, which requires enormous expenditure in terms of personnel costs, maintenance/vehicle costs, and all the infrastructure needed to support permanently stationing a ton of wall-watchers along all 2,000 miles.
And remember, you'd have to still hope that they wouldn't just do something like head over to Mexico's west coast and get in one of those mythical boat things, then travel by water....
PS: The dems have previously offered Trump full funding for his stupid ****ing wall, if he'd sign DACA into law. This could go away at any time Trump wanted it to. That's just icing on this manufactured controversy.
PSS: Remember, the GOP didn't try to pass appropriations when it had the majority of the house. So...
