As has been the case for many years, Mitt Romney’s presidential campaign produced a biographical film to introduce the candidate to the American public, who traditionally start paying attention in earnest to general election campaigns right around Labor Day. The video was a dramatically produced and emotionally moving portrait of a candidate who sought that night to present an image of himself as a warm, compassionate human being that has eluded him throughout his career in presidential campaigning. Inexplicably, the convention planners decided to present this potentially influential reframing of their candidate before the broadcast TV networks started their live coverage at 10 PM Eastern/9 Central Time. Instead, the “big night” led off with an ad-libbed piece of awkward performance art that has become a viral internet punchline and a big regret point for some Republican insiders. Clint Eastwood’s speech featured a cranky, snarky and rambling interview of an empty chair, representing President Barack Obama. Looking back on the fiasco, I’m starting to find the moment an oddly apt microcosm of the 2012 Republican National Convention as a whole: A potentially well-meaning but artificial diatribe against an opponent and actions that don’t actually exist. And this diatribe, while not a new phenomenon, is being executed in a way that may be a watershed moment for the mass-mediated propagation of untruth in American politics.
