I really don't think anyone is taking Trump's misdeeds and poor character into account when making the decision to cross the border illegally or overstay a visa. I'm quite sure they are thinking more about economic opportunities, getting out of a bad situation in their home country, reuniting with family, or other things along those lines.
I’m not talking about what they’re thinking, I’m saying why should immigration laws matter when the President is an actual criminal?
The social contract is: the President isn’t above the law. Right now and as long as he’s President, that contract is breached. So do immigration laws matter? I don’t know, because the plain text of the Constitution says those who swear an oath to the Constitution and foment insurrection against the US shall be barred from office. And yet, an insurrectionist is the executive right now, enforcing laws against people he doesn’t like and waiving laws that make him rich. So then why should immigration laws matter at this time? And under what authority?
