Virginians approved a new congressional map on Tuesday that would aggressively gerrymander the state in the Democrats’ favor, giving the party as many as four more U.S. House seats.

The new map draws eight safely Democratic districts and two competitive districts that lean Democratic, according to a New York Times analysis of 2024 presidential results. It leaves just one safe Republican seat, compared with the five seats the G.O.P. holds on the current map.

The proposed map was drawn by Democratic state legislators and approved by Gov. Abigail Spanberger, a Democrat. It eliminates three Republican-held seats in part by slicing the densely populated suburbs in Arlington and Fairfax Counties and reallocating their overwhelmingly Democratic voters into five congressional districts, some stretching more than a hundred miles into Republican areas.

Perhaps the most extreme new district is the Seventh, which begins at the Potomac River and stretches to the west and south in a manner that resembles a pair of lobster claws. Several well-known Virginia Democrats have already announced their candidacies and begun campaigning in the district.

On the night of her resounding win in last fall’s election for Virginia governor, Abigail Spanberger told her supporters that they had sent a message to the world. “Virginia,” she said in the opening lines of her victory speech, “chose pragmatism over partisanship.”

But even then it was clear that the first big issue of her term would be as partisan as it gets: a proposed amendment by her fellow Democrats to allow them to gerrymander the state’s 11 congressional districts.

The push to redraw the Virginia map was another salvo in a barrage of redistricting spurred by President Trump in a bid to keep Republicans in control of the House in this year’s midterm elections.

Virginians vote on Tuesday on whether to adopt the proposed map, and if the “Yes” vote wins, Democrats could end up with as many as 10 seats, up from the six they hold now. The redistricting battles of the last year would end up in something of a draw, with gains for Democrats in California and Virginia offsetting gains for Republicans in Texas, Missouri and North Carolina — unless Florida lawmakers decide in the coming weeks to draw a new, more Republican-friendly map.

Historically, redrawing of congressional maps has been done each decade after the U.S. census. But with Republicans holding such a slim majority in the House, Mr. Trump began by pressing Texas to redraw its maps, touching off the wave of gerrymandering

Virginia Democratic legislators rolled out their redistricting plan last October, setting in motion the state’s lengthy amendment process just as the campaign for governor was entering its final weeks. At the time, Ms. Spanberger expressed support for the plan, though she emphasized that its passage was up to the legislature and then to the voters.

But even if her formal role in the process was relatively minor — Ms. Spanberger signed the bill setting the date for the referendum — the politics of the effort has loomed over the first few months of her term. Her support for the amendment has drawn accusations of hypocrisy from the right and complaints from some on the left that she has not been outspoken enough in her advocacy.

“There’s always going to be somebody who wants me to do something differently,” the governor said in an interview on Saturday at a rally in support of the amendment outside a home in Northern Virginia. “I will always make someone unhappy, and I will always make someone happy.”

Ms. Spanberger, a former C.I.A. officer and three-term congresswoman, won a 15-point victory in 2025 after running on a campaign focused on pocketbook issues. Centrism has been her political brand since she was first elected to the House in 2018, flipping a district that had long leaned to the right.

Now Republicans campaigning against the amendment have made Ms. Spanberger a prime target, deriding her as “Governor Bait-and-Switch” and highlighting an interview in August 2025 in which she said she had “no plans to redistrict Virginia.”

“This was the perfect opportunity for her to show that she is the middle-of-the-road suburban mom that she portrayed herself as,” said Glen Sturtevant, a Republican state senator. He dismissed the notion that this was an effort that had been thrust upon her, pointing out that she had signed the bill setting the date for the referendum. “She is certainly an active participant in this whole process,” he said.

Republicans have eagerly highlighted recent polls suggesting that Ms. Spanberger’s honeymoon is over, though because governors in Virginia cannot serve two consecutive terms, public approval is less of a pressure point than it might be elsewhere. Some of her political adversaries have tied the drop in her ratings to her involvement in the campaign for the amendment.

But a number of factors are at play in those sagging poll numbers. Some on the right are irked by her support of standard Democratic priorities like gun control measures and limits to cooperation with federal immigration agents.

But some of the most vociferous criticism of her from Republicans, up to and including the president, has been for a host of proposed taxes and tax hikes in the legislature — on everything from dog grooming to dry cleaning — that she in fact had nothing do with. Most of those taxes, which were floated by various lawmakers, never even came up for a vote.

But Ms. Spanberger did not publicly hit back against these attacks until recent days, a delay that some Democrats say was costly.

“She let other people define her,” said Scott Surovell, the State Senate majority leader.

Mr. Surovell’s frustration echoed a growing discontent among Democrats about the governor’s recent moves. For all the Republican criticism of her, some operatives and lawmakers said, Ms. Spanberger has not been aggressive enough in pushing for Democratic priorities, redistricting among them.

This criticism broke out into the open in recent days, after the governor made scores of amendments to bills that had passed the General Assembly. Some lawmakers and Democratic allies accused her of unexpectedly diluting long-sought goals like expanded public sector unions and a legal retail marketplace for cannabis.

“Our party base is looking for us to stand up and fight and advocate and deliver,” said Mr. Surovell, who represents a solidly Democratic district in Northern Virginia. “It’s hard to deliver when you’re standing in the middle of the road.”

In the interview, Ms. Spanberger insisted that she supported the purpose of many of the bills but had to make amendments to ensure that her administration could implement them.

And she said she had been explicit in her support of the redistricting effort, appearing in statewide TV ads encouraging people to vote “Yes” even as an anti-amendment campaign has sent out mailers suggesting that the governor opposes the effort.

But she said she had never been in a position to barnstorm the state as Gov. Gavin Newsom did in the months leading up to the redistricting referendum that passed in California. Mr. Newsom is a second-term governor in a much bluer state, she said, while she only recently took office and has been “in the crush of their legislative session,” with hundreds of bills to read and examine in a short period.

“Those who may not be focused on the governing and only on the politics, they’re going to want me to do politics 100 percent of the time,” she said. “And for people who care about the governing and not the politics, they’re going to want me to do governing 100 percent of the time.”

Her preference, as she has often made apparent, is for the governing over the politicking. But she acknowledged that it is all part of the job.

Asked if she lamented that the highest-profile issue of her term so far was such a polarizing matter, rather than the cost-of-living policies she emphasized on the campaign trail, she said: “Any person in elected office wants to talk about the thing they want to talk about all the time, and that’s it. So I won’t say ‘No’ to that question.”
