Running down the last month of election season, things are about to get cash-money serious as every political actor in the country plows their remaining funds — and likely some borrowed funds, though who knows with this credit crisis — into political communications. Take a look (here for some paper filings that don’t make the electronic databases) at the FEC’s running file of independent expenditure reports in the last week to get a sense of the volumes of money we’re talking about. One interesting tidbit: take a look at the expenditures around Marilyn Musgrave‘s race as a variety of Democratic interest groups weigh in, with Defenders of Wildlife, SEIU and Majority Action throwing well over $1 million in advertising dollars at the race. The Coloradan has some detail.
