The most expensive election in U.S. history

It's an open secret that the presidential election 2004 is the most expensive in the history of the United States. It is just staggering how much playdough the big boys have. As of June 30 President Bush raised a total of 228 million dollar, while Senator John Kerry raised 185 million. But surprise - which candidate was the more successfull fundraiser last month? Check out my chart.
And BTW: The 1996 elections cost around $2.4 billion. The 2000 elections cost around $3.2 billion. How much will the total costes of the 2004 elections be?
