The American Political System (Third core edition; 2018 election update.)

Unlike texts that overwhelm with irrelevant details, Kollman gives students a simple framework, consistently applied: politics is about collective dilemmas and the institutions that solve them.

How can 535 members of Congress get anything done? The committee system. How can the president change immigration policy? Executive orders. How do we get people to the polls? Voter mobilization strategies. Kollman's concise text gets to the conceptual heart of political science.
