Daniel Gross wrote that elections pump a lot of money into the economy, almost all of it spent domestically. According to Open Secrets http://www.opensecrets.org, over $3.6 billion dollars has been spent on the 2010 campaigns as of 15:40 CDT, 26 October. Watching their meter, I'd guess $1,000 is being spent every 13 seconds.
