Mayor Bloomberg to run anti-illegal gun ad during Super Bowl – The biggest score of all at the Super Bowl might be made by Mayor Bloomberg.  In an unprecedented move, the mayor and his national coalition against illegal guns plan to air a 30-second ad during the big game, which draws some of the highest TV ratings of the year and traditionally serves as a platform for memorable and very expensive commercials.  Bloomberg disclosed today that he and Boston Mayor Tom Menino — who serves as both co-chair of the mayor’s coalition and host mayor of the rival New England Patriots — have already filmed the ad that’s going to be screened in selected regional markets on Sunday.
