Study: Obama Bounce Tied to Ad Strategy

President Barack Obama may have his ad strategy to thank for his post-Democratic National Convention 6 percentage point bounce. Both parties avoided a heavy ad schedule during the convention weeks. But Obama and the PACs favoring him aired more than twice the number of ads aired by GOP challenger Mitt Romney and the pro-Romney PACs.

Now, a new analysis is tying that heavier ad schedule to Obama's bounce in the polls. According to the Wesleyan Media Project's analysis of Kantar Media Campaign Media Analysis Group data between Aug. 26 and Sept. 8, Obama and his allies aired 40,000 ads. During the same time, Romney and his allies aired 18,000 ads on broadcast and national cable. That added up to $21.1 million spent by the pro-Obama camp, versus $12.9 million spent by the Romney side.
