Once-in-a-decade redistricting fights begin
Redistricting debates will heat up in many states as Democrats try to stop Republicans, who control most statehouses, from drawing district lines that would solidify their political power for another decade.
Every 10 years, after a new census count, states adjust the boundaries of state legislative and U.S. House of Representatives districts to account for population shifts. The 2020 census was shortened by the pandemic and the results have been delayed, putting some states in a bind: The numbers needed to draw new districts might not arrive until late summer or fall, when candidates typically launch their campaigns.
In states such as Florida, Georgia, North Carolina and Texas that have conservative legislatures and liberal cities, Republicans will try to preserve their majorities by drawing congressional and state legislative districts that favor GOP incumbents and dilute Democratic voting strength.
Midwestern swing states where redistricting battles raged 10 years ago are bracing for a renewed struggle — especially Pennsylvania and Wisconsin, where Republicans control legislatures but Democrats occupy the governor’s office.
“After the red wave in 2011, you had some really aggressive line-drawing in places like Ohio, Wisconsin and Pennsylvania,” said Michael Li, a redistricting expert at New York University’s Brennan Center for Justice, during a seminar sponsored by the National Conference of State Legislatures. “Now I think the hot spots are going to be in the South — North Carolina, Florida, Georgia, Texas.”
Paul Brace, a political science professor at Rice University in Houston, predicted that in the current redistricting process, Southern Republicans may go on the defensive to protect their existing political advantage as cities diversify and attract more Democrats from other states.
“Virginia may have been the tip of the spear,” Brace said. “It transitioned from pretty conservative, to toss-up, to pretty solidly Democratic, driven by migration to cities from other states moving them into the Dem column. That was definitely the case with Georgia, and Texas is on this trajectory as well.”
Texas and Florida also had the largest population growth of the decade, making their latest mapmaking efforts more complex.
In North Carolina and Texas, federal courts over the past decade intervened to redraw Republican-created districts. But the U.S. Supreme Court has diminished the role of the federal courts by eliminating the Voting Rights Act requirement that some Southern states “preclear” their maps with federal officials, and by deciding that state courts should rule on partisan gerrymandering cases.
The Supreme Court dropped the preclearance requirement for states — most of them in the South — with a history of voter discrimination in its 2013 Shelby County v. Holder decision. It also ruled that all purely partisan gerrymandering cases be decided in state courts in Rucho v. Common Cause in 2019.
Another reason state courts will take on a larger role this decade is the increased number of states with new rules for drawing districts, which could attract legal challenges. Ohio, for instance, added a rule that the proportion of Republican- and Democratic-controlled districts should reflect statewide voter preferences. California, Iowa, Montana and Nebraska banned the use of party registration data in drawing districts.
A decade ago, Republicans were savoring their victories from a nationwide offensive called REDMAP (for Redistricting Majority Project), flipping 660 legislature seats and gaining “trifecta” control (both legislative chambers and the governor’s office) of 20 state governments, compared with only 11 for Democrats. Previously, Democrats had trifecta control in 16 states, compared with only nine for Republicans.
Texas saw particularly extensive litigation, with maps drawn, redrawn and redrawn again by federal courts between 2011 and 2018 to correct districts judged to be unfair to racial minorities.
During the last redistricting process, courts intervened to change the maps in a total of 19 states, mostly to make them fairer to Democrats and minority voters. In Maryland, Republican Gov. Larry Hogan in 2019 accused the Democratic-led legislature of gerrymandering and called for an independent commission. The U.S. Supreme Court threw out a challenge to the Maryland maps.
The constant lawsuits and partisan acrimony have prompted some states to take restricting out of the hands of state lawmakers and give it to independent commissions.
In the past decade five states (Colorado, Michigan, New York, Ohio and Utah) adopted some form of commission, compared to one or two in previous decades. In 2018, Missouri voters approved the appointment of a nonpartisan demographer to draw the lines, but in November voters opted to return to a method that will hand the responsibility to panels made up of Democratic and Republican loyalists.
A total of 19 states now have commissions with input on redistricting, and another five use commissions as a backup if the legislature can’t agree or overcome a veto, said Wendy Underhill, director of elections and redistricting for the National Conference of State Legislatures.
“I’ve started to advocate more for a commission, if only because this system makes the branches of government mad at each other,” said Peter Wattson, who worked for the Minnesota Senate from 1971 to 2010 and has become a nationally recognized redistricting expert. Minnesota still relies on legislators to draw the lines. “We could all be friends and blame the commission.”
