Over the past week, presidential candidates John McCain and Barack Obama and their campaigns have spent over $28 million on television advertising. From September 28 through October 4, the Obama campaign spent just under $17.5 million while the McCain campaign and the RNC spent just under $11 million combined. Compared to the first week of September (September 6-13) the amount of campaign advertising has nearly doubled, going from a total of $15.5 million to $28.3 million. During the similar week in 2004, the Bush and Kerry campaigns and their party and interest group allies spent just over $18 million dollars. Indiana, Iowa, Michigan, Minnesota, Ohio, Pennsylvania, and Wisconsin received over half the money spent by the two campaigns on television advertising. During the week, 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. Comparing this presidential election to 2004, the research finds that both the McCain and Obama campaigns have aired more negative advertisements than did their counterparts. In all of 2004, 64 percent of the Bush campaign's ads were negative, while to date, 73 percent of McCain's ads have been negative. Similarly, 34 percent of all Kerry ads were negative while 61 percent of Obama's have been. The McCain campaign cut back on its television advertising in the days following McCain's announcement that he was suspending his campaign to focus on the economy. On September 24, his campaign aired 2,447 ads and on Sept. 25, it aired 1,304 ads. From September 26-28, McCain aired 302, 670, and 852 ads respectively. On September 29, the campaign returned to previous advertising levels, airing 2,687 ads.
