For an event that received such heavy promotion, James O’Keefe’s speech last month at Middlebury College — well, near Middlebury College — seemed anticlimactic.  Mr. O’Keefe, the self-styled undercover journalist whose Project Veritas sting operations try to embarrass media outlets and liberal politicians, showed up in a drab hotel conference room a couple of miles away from campus. Only a few dozen people turned out. He spoke for about 80 minutes and left without much fanfare.  Middlebury is no stranger to speech controversy.
