Politics and Apportionment at the Supreme Court

The Supreme Court could give Republicans another 8 seats in Congress, according to David Wasserman and Harry Enten at FiveThirtyEight. They analyze the possible political impacts of Evenwel v. Abbott, the case testing how to measure population for compliance with one-person-one-vote. Plaintiffs in the case argue that states should be allowed to apportion seats based on where U.S. citizens over age 18 (the voting-eligible population) live, and not on where everyone, including minors and noncitizens, live. The Supreme Court noted jurisdiction earlier this week.
