So I came up with a plan for ending this whole border wall problem. You know, you've got the Democrats saying walls don't work and you've got the Republicans saying walls work. And here's what I propose. Are you ready?

Since we know that Democrats love complicated multivariate prediction models such as for climate change, why don't we create a complex multivariate model or just have science do some studies to find out if walls work? So why don't we commission some scientists to study the effectiveness of walls?

For example, they could run tests where you build a wall and then you have some kind of, let's say, an animal. Yeah, let's say an animal. And you have that animal run as hard as they can into the wall and then you measure how many times it works, how many times does the animal get past the wall by butting its head into it.

Now I'm not suggesting that the human beings at the border are animals. Don't take me out of context. I know you like to do that. I'm just saying that you do animal tests before you do human trials. So we should do some animal testing with walls, see if animals can get over walls first. And if walls stop animals, then we can move on to the human trials where you build a wall and then you say, hey, do you want to go over this wall or maybe you'd like to take a different route?

And then after you've done the studies, that's not enough. You need to do a complicated multivariate model that predicts the future of immigration and all of its impacts, inclu
