This was a fun thread to read. I'll just dump on everyone all at once:
1. This whole "Mueller is mentally feeble" schtick is just beyond stupid. Anyone pushing this should be embarrassed. For shame.
2. Mueller mostly did what he said he'd do, which was not much.
3. If anyone bothered to listen to his answers, at the very least, he made it clear that the Barr interpretation of his report was BS, and the interpretation some of us on here tried to explain to you was the correct one. Anyone still screaming that Mueller "exonerated" the President is lying or being willfully ignorant.
4. Mueller slipped up once, and had to walk back a comment that made it sound like he could, in fact, conclude the President committed a crime, but was prevented from doing so only because of the OLC opinion. Combined with a few other things, I think my original interpretation of the report is still true: for whatever it's worth, Bob Mueller personally believes that Trump committed obstruction. The reason he didn't conclude Trump was innocent was simple: he didn't think he actually was.
5. This did nothing to further impeachment, although it's possible that impeachment was already inevitable, anyway.
6. I still really doubt Trump will ever see the inside of a prison cell.
7. I think the one thing from this investigation that matters most to Mueller has nothing to do with whether or not Trump is going to prison. I think he made it clear that the primary issue we should be concerned with is that foreign powers - particularly Russia - have and continue to interfere with our elections, and we aren't doing enough to stop it. I think Mueller believes this problem rises above partisan concerns.
