Gerrymandering — the dark art of shaping legislative districts to give one party an electoral edge—gave Republicans an outsized advantage in races for the U.S. House and state legislatures in 2016, according to an analysis by the Associated Press published Sunday.
Republican candidates had other advantages, the AP found, from a larger number of incumbents to a voter base spread over more of the country rather than concentrated in cities. Even taking those into consideration, however, AP’s analysis found that gerrymandering handed the GOP a decisive advantage.
