If Dems win the Senate and the Presidency they will be passing a lot of laws very quickly. What they need is a commission on hucksterism and abuse of power so that they can craft laws that make it very difficult for anyone to do this ever again. I think where they'll run into problems is trying to legislate some independence at the Justice Dept. The Courts have basically said that every political appointee works for the president and can be fired at will, and that this is baked into the constitution. No matter how big a wave the Dems can pull off I just think the Big Sort has more or less made new constitutional amendments DOA for the time being. I think where they can have a big impact is in disclosure laws, nepotism laws, limiting executive fiat, and so on. And yes, Trump has shown that the president has the full authority to ban (or grant) any security clearance he pleases, and there's no other sane person in America who would give Kushner security clearance. Trump's own DoJ told Kush to fuck off until he intervened. Even if they didn't revoke Big Don's credentials, he would no longer have the right to declassify whatever he wants willy nilly as he can now. We're going to have a lot of spring cleaning in 2021, god willing.
