Optimistic, and a good example of the "bubble effect" created by the concentration of the chattering classes in New York, Washington and California.   Removing Trump for obstruction of justice would be difficult even if the Democrats had Congressional majorities.  By its very nature, activity in cyberspace,  the Russian connection seems likely to be eminently deniable and  open to multiple interpretations no matter what Mueller may believe he has found.  Add that Trump's core vote (a) won't believe a word of anything proved against him (b) control the renomination of most Republican Congressmen, and Trump seems likely to stay unless he does something unforgivable in plain view of millions.

I liked the crack about mirrors and books.
