Tom is absolutely right that the manipulative use of graphical filters has a long (if not exactly proud) pedigree in politics. What he’s forgetting, however, is that hysterical over-reaction to political advertising also has a long pedigree. Does no one remember RATS? Or Michael J. Fox’s exaggerated Parkinsons symptoms? Making mountains over molehills is the whole point of a political campaign. This campaign has had its stupid moments, but they’re no stupider than past contests.
