I think they're focusing on the evil empire/old Cold War resentment aspect of it too much at the expense of the much more compelling "Trump has something to hide"/cover-up/perjury aspect.
I disagree, they are really focused on the "hiding" aspect. You can't turn on a news program without a democrat calling for a independent investigation. I like the way Maddow has been covering it lately, It makes more sense on that Trump is colluding with the Russians on a corruption is mostly driven by financial/oil corrupt incentives rather than a realignment for American foreign policy
Maddow's coverage has been particularly good recently, I agree.
She (which really mean that she has some good accountants on her staff) has followed the money. Money is the truth behind many high-value crimes because a crime involving big money is tricky to hide.
