The North Carolina General Assembly passed new redistricting maps Thursday, laying out the state’s political landscape for the decade to come.

The new maps likely create a 10 to 4 split for Republicans in North Carolina’s congressional delegation and the GOP will hold onto its majorities in the state House and Senate.

The three maps passed on party-line votes. The governor has no veto power over redistricting.

North Carolina has a long history gerrymandering, drawing maps to basically pick which party will win. Both parties have done it when they’ve been in power. The maps drawn after the last census in 2010 led to a political and legal fight that lasted almost a decade.

What You Need To Know

  • The Republican-led General Assembly passed new redistricting maps for legislative and congressional districts Thursday

  • The congressional map means Republicans will likely win at least 10 seats out of 14, according to analysis from researchers at Duke and Princeton

  • The state House and Senate maps will also allow Republicans to hold onto control in both chambers of the General Assembly

  • The maps are already being challenged in court for gerrymandering and more lawsuits are likely

One lawsuit has already been filed, before these new maps were even finalized, accusing the Republican-led General Assembly of illegal gerrymandering.

“We found that the map that has been proposed for the North Carolina House really dramatically under-elects Democrats. We have similar analysis for the Senate,” said Jonathan Mattingly, a Duke University mathematician who uses mathematical models to analyze gerrymandering.

He testified in court cases that found North Carolina’s last set of maps were unconstitutional.

The maps have been widely criticized by Democrats and academics that study redistricting and gerrymandering.

“Free and fair elections are the cornerstone of our democracy and we can’t have fair elections without fair maps. North Carolina is an evenly divided state, and we should have a congressional delegation that reflects our citizens,” Rep. Deborah Ross, a Democrat, said in a statement Wednesday.

North Carolina House Speaker Tim Moore, a Republican, defended the maps.

“I am confident that the House and Senate have approved redistricting plans that include maps that are constitutional in every respect,” Moore said.

The nonpartisan Princeton Gerrymandering Project gave all three maps, for state House, Senate and Congress, an “F” grade, finding “significant Republican advantage” in each.

“I think it's really important not just to count seats, but to see how people have been put into districts. With the (congressional) maps we've been given, the districts that are in play have many, many less Democrats than one would typically see,” Duke’s Mattingly said.

"The districts that are very safe for Democrats have a lot more Democrats — so they've been packed in. And the districts that are very safe for Republicans actually have less Republicans, still leaving them safe. And this is really kind of one of the hallmarks of a map that's gerrymandered,” he said.

Despite the legal challenges already filed, the maps probably won't change before next year's elections, said Michael Bitzer, a political scientist at Catawba College who just published a book on the history of redistricting in North Carolina.

“Unless there’s egregious maps,” Bitzer said in an interview last month. The courts “would let the process play out with maps that are being challenged,” he said.

The new congressional map will likely be a 10-4 or 11-3 split in favor of Republicans.

Congressional map

Based on analysis from Duke and the Princeton Gerrymandering Project, North Carolina’s new congressional map will likely lead to electing 10 or 11 Republicans and three or four Democrats.

The congressional map divides the Triad’s urban areas, a particular concern for Democrats, who fear that it could dilute their voters in the Greensboro and Winston-Salem areas.

"These congressional maps represent an extreme partisan gerrymander that splits communities of interest," said Rep. Kathy Manning, a Democrat representing the Triad area.

"Under these maps, Guilford County is split into three congressional districts, diluting my constituents' interests and lumping them in with far-flung counties in the western mountains, the suburbs of Charlotte, and as far east as Wake County," she said. "These maps don't acknowledge that the Triad is a region with shared interests, concerns and needs."

Manning’s 6th Congressional District is split in the new map, putting Democratic-leaning urban voters in with more Republicans.

"These maps were created for one purpose only: to ensure Republicans win more House seats so that they can recapture control of the U.S. House of Representatives," Manning said in a statement.

Rep. G.K. Butterfield’s seat in Congress could also be in play for Republicans. Butterfield, who was first elected to Congress from northeast North Carolina in 2004, is on the list of seats the National Republican Congressional Committee plans to target in 2022.

The biggest change in Butterfield’s district is moving Greenville and most of Pitt County into another district.

“It takes thousands of Democratic voters out of my district and places those into another district, which means my district becomes less Democratic and less African American,” Butterfield said in an interview with Spectrum News 1 after the maps were approved Thursday. He argued that the new map violates the Voting Rights Act by diluting Black votes.

“It’s called racial gerrymandering, it’s called political gerrymandering. It’s unacceptable, it violates the law, and we are going to challenge it,” he said. “This is a state that is evenly divided between Democrats and Republicans, and yet the Republican legislature draws the map that gives the Republican Party a clear partisan advantage and it’s unacceptable.”

The new map also puts Rep. Alma Adams, a longtime Charlotte Democrat, in the same district as Republican Rep. Dan Bishop. Bishop's campaign tells Spectrum News he will move so he can run for office in what is now the 8th Congressional District to run for re-election in 2022.

The new map for North Carolina Senate districts will allow Republicans to hold onto their majority and potentially get a supermajority.

North Carolina General Assembly maps

Like the congressional map, the Princeton Gerrymandering Project gave the state legislative maps an “F” grade overall and in partisan fairness.

“The state legislative maps would put Republicans at or within reach of veto-proof majorities in both chambers,” said Asher Hildebrand, a former chief of staff for Rep. David Price who now teaches politics at Duke University.

According to the Princeton University project, the new North Carolina House map will likely have 70 districts for Republicans and 50 for Democrats. There are 17 seats that are considered competitive.

For the North Carolina Senate map, the Princeton researchers say Republicans would likely win 30 seats and Democrats 20. They say seven seats in the state Senate could be competitive.

If Republicans can win the competitive seats in the House and Senate, they could gain supermajorities to overcome any vetoes from the governor.

The new districts for the North Carolina House will keep Republicans in power, according to analysis by researchers at the Princeton Gerrymandering Project.
