The 9/11 conservative shift

This study analyzes the causal impact of the 9/11 terror attacks on individual political orientation and political support intensity using the German Socio-Economic Panel 1999-2003. Exploiting survey interview timing in 2001 for identification and controlling for unobserved individual heterogeneity, I find 9/11 to have increased overall political mobilization. While there is no indication of a considerable switch in support between political blocks, the attacks significantly weakened support intensity among left-wing voters and increased the strength of political support among right-wing voters, indicating a shift in conservative direction.
