The Republican nominee appeared before a rich, mostly white, mostly Republican, mostly Catholic audience  -- and managed to get booed.  On the one hand, this unlikely (in any other year) scenario exposes once again (as MSW rightly says) the boorishness of Donald Trump, his remarkably poor judgment, temperament and timing; on the other hand, the reaction of the audience to his boorishness is reassuring: most people, regardless of politics, religion, or social status, are fundamentally decent and still capable of righteous indignation when face-to-face with someone who isn't.  One would hope -- but unfortunately not expect -- that Catholic clerics, especially bishops, who have been explicitly or implicitly supporting the candidacy of the fascist, racist, xenophobic, misogynistic know-nothing Republican nominee will apologize and stand down.
