Since the Huffington Post premiered, it has been home to plenty of ludicrous speculation. Today Steven Rosenbaum earns a place in the Huffington Hall of Fame for claiming John McCain will drop out at the convention as part of a September Surprise by the Republicans. The creator of MTV UNfiltered, which is kind of like journalism, tells readers, "I think there is every reason to believe John McCain won't be the nominee." Yet he doesn't cite a single reason. So idiosyncratic is Rosenbaum's thesis that his so-called September Surprise will allegedly take place in mid-August, when McCain will abruptly announce his withdrawal from the race. None of the substitute-candidates Rosenbaum names are more media-savvy and electable than the maverick moderate. Perhaps Rosenbaum is just projecting his own insecurities about his party's nominee, the utter chaos of the Democratic primary, and the disarray of planning for the Denver convention.
