The Sun-Times reports that US Senate candidate Barack Obama is being followed by a particularly persistent cameraman, whose job is to record every single second of Obama's appearances in public. The cameraman, not surprisingly, is employed by Obama's opponent, Republican Jack Ryan. A spokeman for Ryan's campaign says that they're just making sure Obama doesn't contradict himself in his public statements. And I'm sure that, if Ryan catches Obama in a misstatement, he will quietly and discreetly alert Obama's team to the error, without notifying any people in the news media or making a big deal about it. Update: Jack Ryan has apologized, and has ordered the cameraman to back off.
