Over in Data Points today (in the center column of U.S. News's Opinion page), we've got some comparative figures. John Kerry spent $310 million in the 2004 election, for example, or about twice as much as Obama raised last month. George W. Bush and Al Gore combined to spend almost $240 million in 2000. And they were big spenders: Bill Clinton and Bob Dole (or as I like to call him, John McCain version 1.0) combined for $239.9 million in 1996.
If you really want to get weirded out, consider that Obama raised more in September than Ronald Reagan and Walter Mondale spent all told in 1984 ($103.6 million) and roughly as much as Jimmy Carter (two runs), Reagan, and Gerald Ford spent in the 1976 and 1980 presidential campaigns combined.
The mind reels.
