The Paradox of Redistricting: How Partisan Mapmakers Foster Competition but Disrupt Representation

The authors examine constituency changes induced by redistricting and ask three questions:What explains the amount of instability and uncertainty induced by redistricting? Does uncertainty affect legislators’ career choices? How do these changes affect election outcomes? The authors show that partisan redistricting plans are able to produce significant instability between elections, especially for opposing-party incumbents. Their findings have important implications for representation: through redistricting, strategic actors can disrupt the stability that many theorists would consider paramount for the operation of a democratic republic. The authors show that the effects of redistricting go beyond the simple examination of changes in each district’s underlying partisanship.
