This study investigates how US members of Congress respond to battlefield casualties in their districts during the Iraq War. It posits that while partisanship shapes aggregate congressional views, all representatives are influenced by local deaths and tend to criticize the war more intensely.

The research analyzes an original database of over 7,500 coded House floor speeches on the Iraq War. The findings demonstrate strong support for both hypotheses: partisan divisions affected overall policy positions, but battlefield casualties consistently led increased criticism from all representatives regardless of party.

Democrats in districts with high casualty rates showed significantly more anti-war voting patterns than their peers elsewhere. Most importantly, this variation in congressional anti-war sentiment strongly correlates with geographic differences in public war support as measured by the original data.
