The thing is, nothing in here tells us anything about Trump we didn't already know. Mueller was not on a crusade, and he did what he is supposed to do. I question the DOJ's position that they cannot bring charges against a sitting president, but that was decided back in 2000 (under W) and isn't up to Mueller to decide. So he was careful to stay within the bounds of what he is legally allowed to do, although I think it comes through pretty clearly that he thinks Trump obstructed justice.

But to me, the left's hope in Mueller as somehow causing a great deal of change was always going to be misplaced. No one who supports Trump was going to be convinced no matter what Mueller said, whereas no one else was waiting on Mueller to conclude that Trump had colluded with the Russians. Mueller showed clearly that there was collusion in the common use of the term, but there's enough wiggle room here for any Trump supporters to justify saying that the whole thing was a political ploy.

As for what we do? Keep calm and carry on. Vote. Try to not be terrible to each other. Avoid pretending that we have more influence over broader events than we do.
