How will the most competitive races shape the post‑Callais v. Louisiana redistricting cycle next year?
The Governors’ races are plentiful in 2026, with 36 statewide chief executive contests heading toward conclusion. How the most competitive races will shape the post‑Callais v. Louisiana redistricting cycle next year is a key question the new Governors will partially answer. The 2026 map is unusually symmetrical: of the 36 races, 18 are in Democratic‑held states, 18 in Republican states, and exactly half are open‑seat contests.
With Democrats primed to take the House majority in the new Congress, redistricting will again be a major factor in the 2028 election cycle. The landmark Supreme Court decision last April on the Callais case effectively eliminates the need to create protected majority minority districts, giving states the opportunity to bring their congressional and state legislative maps into compliance with the new redistricting criteria.
Republican‑led states will have incentive to adjust their maps to limit Democratic gains to a single cycle, while Democratic‑led states will seek to make their newly elected members more secure heading into 2028.
Of the 36 gubernatorial races, 15 appear competitive or moderately competitive. In those states, the 2026 outcomes could materially influence the 2027 redistricting picture. Redistricting will not occur in two of the competitive gubernatorial states, Alaska and Vermont, because both have at-large congressional districts.
Arizona
Gov. Katie Hobbs (D) is in a competitive race but continues to hold polling leads over US Rep. Andy Biggs (R‑Gilbert), thus positioning her as the favorite for re‑election based on current data. Republicans maintain narrow majorities in both legislative chambers, but if Democrats were to gain control in November, movement on redistricting could follow.
Arizona was one of the first states to adopt an independent citizens’ redistricting commission, yet the 2026 cycle has shown that several states have found ways to maneuver around their commissions in order to implement new maps.
Florida
Polling shows a close Governor’s race in early October, but pollsters have badly missed the Florida elections for the past four cycles. Republicans have big majorities in both legislative chambers, so it is unlikely that the state will be a factor in 2027 redistricting irrespective of the gubernatorial outcome.
Georgia
Georgia was among the states that initially considered redrawing its maps after the Callais decision, but legislative leaders ultimately chose not to proceed. They later announced plans to call a post‑election special session, yet no such scheduling action has been taken.
If Democrat Keisha Lance Bottoms were to win the Governor’s race, legislative leaders would likely move quickly to convene and advance a map designed to add two Republican seats while Gov. Brian Kemp (R) remains in office.
Iowa
Democrat Rob Sand is well positioned to win the governorship, but it remains unlikely that redistricting will occur in a state that has effectively ceded the map‑drawing process to a legislative algorithm. Republican majorities in both legislative chambers are strong, so even with a Sand victory, it is improbable that we will see a redistricting effort regardless of how the competitive congressional elections unfold.
Kansas
Democratic Gov. Laura Kelly is term‑limited this year, giving Republicans a strong opportunity to reclaim the governorship. In most polling, state Senate President Ty Masterson (R‑El Dorado) holds an advantage over state Sen. Cindy Holscher (D‑Olathe). With Republicans maintaining solid majorities in both legislative chambers, a Masterson victory would likely place redistricting on the table for 2027. The result could be a one‑seat Republican gain.
Michigan
Secretary of State Jocelyn Benson (D) is poised to succeed term‑limited Gov. Gretchen Whitmer (D), placing the focus squarely on the legislature. Democrats hold a narrow majority in the state Senate, while Republicans control the House. If the latter chamber flips, Democrats could attempt a redistricting move.
Michigan has an independent redistricting commission, but as noted earlier, several states have successfully maneuvered around their citizens’ panels in 2026. Should Democrats capture the state House majority, Michigan will become a state to watch in the redistricting arena.
Nebraska
Gov. Jim Pillen (R) faces competition in this cycle but is still expected to prevail. Republicans were just one vote short of advancing a redistricting plan in 2026, so any changes in the unicameral legislature could determine whether a new map is implemented. With the open 2nd District likely to elect a Democrat next month, Republicans would have added partisan incentive to pursue a redraw in 2027.
Nevada
Gov. Joe Lombardo (R) is in a tight re‑election campaign, and if Democratic Attorney General Aaron Ford were to unseat him, redistricting could quickly emerge as an issue in the new legislative session. Democrats appear positioned to retain their majorities in both legislative chambers.
Should they also capture the state’s lone Republican congressional district, the Reno‑anchored 2nd District, a Democratic legislature and Governor would likely move to redraw the map in order to make that seat more secure for their new Representative. Whether redistricting occurs in 2027 will largely hinge on the gubernatorial outcome.
New York
The Empire State will be particularly interesting to watch next year on the redistricting front. Gov. Kathy Hochul (D) is favored to win re‑election, and the legislature will remain solidly Democratic. Although New York has a redistricting commission, Democrats believe they can draw additional Democratic‑leaning districts.
Their challenge, however, is the state’s significant population loss concentrated entirely in New York City. According to mid‑decade Census Bureau estimates, New York has lost more than 200,000 residents, all from the City, while the rest of the state has experienced modest growth. As a result, efforts to increase Democratic seats when the party’s anchor population base is likely to lose representation in the next apportionment may prove more difficult than a cursory overview suggests.
Ohio
The Buckeye State conducts redistricting through a bipartisan commission composed of seven elected officials. Because the panel adopted a new map with unanimous support earlier this year, that plan can remain in place for the rest of the decade. As a result, it is unlikely the Commission will reopen the contentious process in 2027.
Oregon
Democratic Gov. Tina Kotek is unexpectedly locked in a very tight re‑election race, but redistricting is unlikely to occur regardless of the outcome. The Democratic majority has already maximized its advantage under the current congressional map, leaving little room for improvement. As a result, a 2027 redistricting effort does not appear likely.
Texas
Gov. Greg Abbott (R) is likely to win a fourth term, though by a closer‑than‑expected margin. Republicans will retain control of the state Senate, but their House majority may narrow. Because the congressional map was redrawn this year, it is unlikely that redistricting will make a return appearance in 2027.
Wisconsin
In Wisconsin, the gubernatorial and legislative elections will directly determine whether redistricting occurs. The state Supreme Court declined to act on a case that could have triggered a redraw this year, so a Democratic sweep in November is the most plausible path for redistricting to move to the forefront in 2027.
The Governor’s race between Milwaukee County Executive David Crowley (D) and U.S. Rep. Tom Tiffany (R‑Minocqua) remains tight, and Republicans currently hold tentative majorities in both legislative chambers. Should Democrats gain control and pursue a redraw, they could potentially add two congressional seats.
