Voters in Virginia on Tuesday were projected to approve a constitutional amendment paving the way for new congressional maps to be used in this year’s midterms, the latest turn in the monthslong redistricting wars playing out across the country.

Democrats could gain up to four seats in the House of Representatives through the new Virginia maps. The ballot question was a closely followed contest in a state that was one of the Democrats’ last remaining opportunities to make congressional districts more favorable to the party ahead of the midterms.

Virginia Democrats currently hold six of the state’s 11 congressional seats. The new maps would make 10 seats Democratic-leaning, based on recent voting history, with one district in the southwest part of the state remaining heavily Republican.

“Virginia voters have spoken, and tonight they pushed back against a President who claims he is ‘entitled’ to more Republican seats in Congress,” Virginia Gov. Abigail Spanberger wrote on X shortly after the race was called. “As we watched other states go along with those demands without voter input, Virginians refused to let that stand. We responded the right way: at the ballot box.”

While the decision over whether to redistrict was left to Virginia voters, national figures were quick to weigh in and hit the campaign trail for the redistricting referendum. On Monday, President Donald Trump and House Speaker Mike Johnson held a tele-rally to campaign against it. Over the weekend, Democratic Virginia Gov. Abigail Spanberger, Maryland Gov. Wes Moore and House Minority Whip Katherine Clark held separate events encouraging Virginia voters to vote yes.

President Barack Obama, who appeared in an ad for both the Virginia redistricting campaign and California’s Proposition 50, wrote on X shortly after the referendum passed that “Republicans are trying to tilt the midterm elections in their favor, but they haven’t done it yet.”

“Thanks for showing us what it looks like to stand up for our democracy and fight back,” he wrote.

The Virginia redistricting push is the largest by Democrats after California’s Proposition 50, which passed overwhelmingly in a November special election. But Virginia is a much more competitive state, making the referendum a much more competitive contest.

The measure’s ultimate fate is still playing out in court. The Virginia Supreme Court allowed the referendum to move forward to a vote while it weighs the redistricting amendment’s legality. At the center of the dispute is the “process, not the outcome,” that Democrats followed in the state Assembly in order to hold the referendum, the justices wrote in their ruling.

“Today, the referendum portion of this fight is behind us,” Chairman of the Republican Party of Virginia, Jeff Ryer, wrote in a statement. “Now, we enter the phase that will be decided through litigation.”

Even if the courts uphold the amendment, the state will return to its standard redistricting process — with lines drawn by a bipartisan redistricting commission — after the 2030 census.

Virginia Democrats announced plans in late October to redistrict, a move that surprised many at a time when attention was centered on Illinois, Maryland and California as the likeliest blue states to do so.

At the time, the Virginia state Senate’s top Democrat, Majority Leader Scott Surovell, said the redistricting push was meant “to address actions by the Trump administration.”

The next state that could redistrict is Florida, where lawmakers are set to take up the topic next week as part of a special session called by Republican Gov. Ron DeSantis. State lawmakers could add anywhere from two to five Republican-friendly seats.

“We will crush the DeSantis Dummymander in Florida next,” House Minority Leader Hakeem Jeffries wrote in a post on X following Tuesday’s results. “Maximum warfare, everywhere, all the time.”

Key to the redistricting battles is also a pending Supreme Court decision over a provision in the Voting Rights Act that prohibits racial gerrymandering. If the Supreme Court overturns the provision, other Republican states may move to redistrict ahead of the midterms as well.
