Nearly every TV ad Republican John McCain ran last week was negative, compared to just 34 percent of those by Democrat Barack Obama, according to an analysis released Wednesday.
The harsher tone in McCain’s ads mirrors the sharper attacks he and his running mate Sarah Palin have been making on the campaign trail as polls show Obama opening up a lead.
Obama also has a lead in fundraising, which is letting him do more advertising than McCain, the Wisconsin Advertising Project report said.
