I never ever ever want to hear anymore excuses from democrats about "oh, but we did kinda do the one thing. Governance is hard, and we just couldn't get 100% of Congress to agree. The republicans bullied us until we came and we're all out of gas :("
I mean, this isn't really governance. It's Trump signing an executive order that will never come to pass without an constitutional amendment, which isn't going to happen. Trump might have promised to be a dictator on day 1, but no matter how much he fancies himself a king, he will always have to work within the boundaries of the framework of government, no matter how ratfucked it might be. Expect this one to be struck down in court very quickly.
With this SCOTUS, nothing is ever completely off the table, but I'd like to think that they wouldn't make a sweeping decision like that which could potentially call into question the legitimacy of the citizenship status of hundreds of millions of Americans (including their own) just for the sake of appeasing Trump.
