Is The Mueller Report More Damaging Than Barr's Summary Indicated?

Maybe
It'd almost have to be, given that the summary was so good for Trump.
As for whether it needs to be released now or later: later's fine with me, FWIW. I've said that there should be massive protests if the report isn't released. And I still think that. But I now don't think there's any chance of it not being. I also think it's ridiculous to make a bid deal out of another two weeks.
