NOTE: Totals represent spending in calendar year 2010 and will change as new filings are made or information is amended. Data includes "electioneering communication" and electronically-filed "independent expenditure" spending reported to the Federal Election Commission. Spending on "issue ads" targeting candidates will not be included if it is more than 30 days before a primary or more than 60 days before the general election. "Weeks on list" shows the total number of weeks that a group or race has been in the top ten throughout the year.
