Sen. Obama was somewhat misleading when he claimed 100 percent of Sen. McCain ad’s were negative. His claim is backed up only in so far as it regards a single week examined by the Wisconsin Advertising Project of the University of Wisconsin. In an Oct. 8 report, they concluded that, “during the week of September 28-October 4, nearly 100 percent of the McCain campaign’s advertisements were negative. During the same period, 34 percent of the Obama campaign’s ads were negative.”
