We explore differences in perception of national security policies between self‐identified liberals, moderates, and conservatives from a national sample of U.S. adults. Using a discrete choice experiment, we also quantify each group's willingness to trade off select policies in exchange for reduced risk of a 9/11‐style terrorist attack. Relative to other groups, liberals are more likely to view such policies as ineffective and susceptible to government abuse. They also perceive a lower threat of terrorism. All groups are willing to make trade‐offs between civil liberties and risk of a terrorist attack. However, loss of civil liberties affects liberals more than conservatives. (JEL D61, H41, H56)
