Outside groups, including both national parties and special interests, are spending almost $1 million more in Indiana's three competitive House races than the actual candidates. An examination of FEC filings by the Indianapolis Star reveals that the most independent expenditures are in the 8th District, where GOP Rep. John Hostettler is struggling to maintain his seat against Dem Brad Ellsworth. Democratic groups have spent $2.6 million in the district compared to $1.9 million by Republicans. Liberal groups are also outspending conservatives in the 2nd District race between GOP Rep. Chris Chocola and Dem Joe Donnelly. In contrast, GOP backers are dominating the 9th District battle between Republican Mike Sodrel and Dem Baron Hill. All three races are in the top 15 of the National Journal's rankings for likely seat changes this year.
