Our new book is titled Divided We Stand: The 2020 Elections and American Politics. Among other things, it discusses state and congressional elections.
Despite the persistence of partisan gerrymandering, between 216 and 219 congressional districts, out of the 435 nationwide, appear likely to tilt toward the Democrats, according to a New York Times analysis based on recent presidential election results. An identical 216 to 219 districts appear likely to tilt toward Republicans, if the maps enacted so far withstand legal challenges. To reach a majority, a party needs to secure 218 districts.
...The relatively fair map is something of an accident. Democrats and Republicans again drew extreme gerrymanders with twisting and turning district lines, denying many communities representation in Congress. Dozens of incumbents were shielded from serious challenges. The number of competitive districts declined.
But, unlike in previous cycles, both parties’ extreme gerrymanders have effectively canceled each other out — in no small part because Democratic lawmakers went to greater lengths to maximize their advantage. And more states are having maps drawn by courts or by nonpartisan and bipartisan commissions than in previous decades, reducing the number of districts drawn to intentionally advantage one party.
