The politics around immigration in this country continue to get more and more abstract. Democrats have succeeded in making it into a racial "culture war" issue instead of talking about its basic national security or economic considerations.
This is objectively false. Democrats have done no such thing, nor have they ever intended to. Pete Wilson, Pat Buchanan, Rush Limbaugh, Lou Dobbs, Tom Tancredo, Joe Arpaio, Donald Trump, Steve Bannon, Stephen Miller - not Democrats.
But you know this. So I can only assume you are arguing in bad faith.
