Plus why should he root for a bill that ties his hands as President?

Because there's plenty of room for a bill that doesn't tie his hands as President, and because this is supposedly an urgent crisis right now. No matter what happens in the election, Trump won't be President for a full calendar year.

We're being played. Why can't you see that?

Because it's not true. "Mass upheaval" isn't the only criteria for being able to claim asylum, and (once again) nearly all asylees end up showing up for all of their court hearings and a huge chunk of them end up winning their asylum cases in front of a judge despite their lack of resources in the judicial system.

You're being played, I'm afraid. You've been told over and over again that all of these asylum claims are pretextual, and you've never bothered to check whether that's true. So you've formed a worldview about asylees that's simply inconsistent with the results from literally hundreds of thousands of asylum hearings, but you're going to stick with it.
