https://www.businessinsider.com/trump-is-more-worried-about-michael-cohen-than-robert-mueller-2018-4 Look at it this way: Russia is "did the Trump campaign talk to the Russians." Yes, obviously. Trump is quite fuzzy on what that means to him, and the country in general is, too. From a foreign influence standpoint it's a big fuckin' deal but from a Trump standpoint it's not like he's Boris and Melania is Natasha. Although that's an awesome image. The Cohen investigation, however, is "Trump's personal fixer for ten years has flipped to Federal and State investigators." This is a president whose tax returns are... ugly. We don't know how ugly, we don't know why, but we know he's been fronting for Russian oligarchs for a long, long time. We're more interested in Russia. From Trump's personal standpoint, Cohen provides a lot more personal jeopardy.
Yeah, that's how I see it. Cohen was privy to a lot of Trump sausage-making over the last several years. That's why I expect Trump to do something desperate soon. At that moment, the GOP are going to be put in a serious quandary. Trump's desperation is going to signal that he's trying to hide some serious shit. At that moment they have to fold or raise.
Mueller has Trump in a fork: he can either sacrifice his rook and throw his full weight at dealing with whatever revelations Cohen has about Trump's finances, or he can sacrifice his queen and throw his full weight at the Russia investigation. He can't divide and conquer: it's clear that the Trump administration is already over capacity with bimbo eruptions and the dike now has two big holes in it. It's starting to look like encirclement. I hope I'm right.
