Jonathan Chait lays it all out in this article, and Trumps involvement and contacts with Russia is pretty startling when you put it all in one place.
Josh Marshall has a really good take on this. You really have to rely on some magical thinking and special pleading to explain all of this away. If you just accept that Trump is compromised by Russia then things get much simpler and make a lot more sense. The short version, the worst case scenario is a lot more likely than an innocent explanation.
My big takeaway reading his narrative is one I’ve been convinced of for months. Individually, each guilty-seeming or suspicious action, each lied-about contact or unexplained meeting can be explained by some heroic theory of Trump’s idiosyncrasy. So maybe Trump didn’t have anything to hide in the Russia investigation. But the drive for control and loyalty made him take actions which made him seem guilty. Or Trump’s inexplicable obsession with and need to gratify Vladimir Putin may seem suspicious but is really just his fondness for authoritarian leaders or a need to show that he’s not cowed by the Russia probe.
Each of these theories are possible. But in each case an implausible and heroic theory is ushered in to avoid the more elementary explanation: that Trump has something to hide and some deep attachment to Putin.
It reminds me of looking at geocentric and heliocentric models of the solar system. Before the Early Modern Era, the Ptolemaic geocentric system had a great run. And it worked. It correctly predicted where given stars or planets would be in the sky at different dates and times. But to make everything work with the Earth at the center of the solar system, the standard elongated oval orbits we know wouldn’t get it down. You needed orbits within orbits and some heavenly bodies that marched in one direction and then turned and started marching in the other direction. It was highly convoluted and required a lot of astrophysical special pleading to make everything fit. If you just put the sun at the center of the solar system everything got much, much simpler.
As you probably intuited, forcing the Earth to be at the center is a bit like insisting on an innocent, trail-of-a-thousand-misunderstandings-and-flukes explanation of all the secret meetings, pay offs, lies and coverups we see everywhere we look in the Russia story. If you consider the possibility that Trump did something very bad and is doing everything he can to hide it, suddenly a lot of facts which otherwise require all sorts of rejiggering and creative thinking just fall into place.
