From the Center for Responsive Politics. Year-end lobbying reports for 2007 are still trickling out from the Senate Office of Public Records. The total spent on federal lobbying last year is now up to $2.3 billion, but we know there are still reports that haven’t been made available electronically yet. Based on the 2006 total, the missing data for ’07 could total $300 million or more. We’ll update OpenSecrets.org’s Lobbying Database again next week with any new data.
