Blue Rider / Red Poster

From Google street view, here's a remaining sign for the Blue Rider Theatre:

I read a poem at a memorial service there once.

The place is in the fringes of the news because our president once watched and discussed a play there about Saul Alinsky.

I can't see much coming of it. The play had a revolutionary-looking sixties-style poster, and it had the president's name on it, misspelled as "Baraka", and I guess it's an okay visual for opponents who want to paint him as a revolutionary, but, really, it's not that great a visual. Is it?

In search of a smoking gun?
I don't think it's much of one.
