Whatever happened to the bulge on President Bush’s back, visible in the Presidential debates? It was referred to by the usual family of -Gates: AudioGate, PrompterGate, and, my favorite, “The Battle of the Bulge.” I had followed the story develop first-hand on various blogs, and saw how it played out in the national media, fading out by election day. It’s returned to the news, briefly, courtesy of a Dan Kennedy column in the Phoenix. I thought I’d take another look at the story, and try to answer the question as to why the Internet blogs, for all their supposed powers, could not shake the truth out. This is part of a series on “Truth Exposure: Getting the Facts to Light.”
