The advent of television news added movement. But fake "news events" designed simply to attract news cameras and garner free publicity have come to dominate and deteriorate American politics more every year, draining most semblance of serious substance.
Barack Obama used photo ops endlessly when he was president, often flying four hours round-trip at $210K an hour for a 20-minute photo-op to inform workers that hundreds of thousands of jobs were due any minute due to his trillion-dollar stimulus program.
If not run right, however, photo ops can suddenly turn on a politician and bite their South Side — in front of the same leering cameras. Ask Hillary Clinton after her awkward Thursday experience attempting to enter the New York City subway.
