How the 2026 Senate Races Will Shape the Federal Courts

Most people think of individual Senate races as a fight over who controls the chamber. They also shape the federal bench of the respective states. District judges are nominated by the president and confirmed by the Senate, and home-state senators have traditionally had a big say in who gets picked for their own state’s federal courts via the blue slip tradition.1 So when a Senate seat changes hands, the influence over that state’s judgeships can change with it. We at Judicial Hub have created two features that let you call all 35 races yourself, start from the current delegations or a competitive forecast, or run a simulation and watch the results come in. As you go, you’ll see how many judgeships, and how many judges eligible for senior status, end up under Republican, Democratic, or split delegations. In addition, we are breaking down the judicial stakes in every competitive Senate race.

Key Facts

  • Federal judges serve for life, but can assume senior status, which keeps them on the bench with a lighter caseload and opens their seat for a new nominee. To qualify, a judge must be at least 65, have at least 10 years as a federal judge, and have an age plus years of service that equals at least 80.
  • Under the blue slip tradition, the Senate Judiciary Committee will not hold a hearing on a district court nominee unless both of the nominee’s home-state senators approve.
  • Senators elected in November take office January 3, 2027 and serve until January 3, 2033. The exceptions are the special elections in Ohio and Florida, whose winners fill terms ending January 3, 2029.

Alaska

In The Last Frontier, the Democratic Party is fighting to “flip” the state’s Senate seat with former at-large House Representative Mary Peltola against incumbent Republican Senator Dan Sullivan (not to be confused with Daniel J. Sullivan Jr., another candidate on the ballot).2 Polling shows a very close race with Peltola leading by two points.3 Democrats have not won a Senate election in the state since 2008, so if Democrats do flip the seat, the repercussions will be far-reaching, including the shaping of the state’s only federal district court. The judicial stakes for the state are very much present, as there is currently a vacancy on the three-judge bench along with one judge eligible for senior status. The Trump administration is hoping to fill the vacancy when the Senate returns next month with nominee Kyle F. Reardon.4 This would make it two judges appointed this term after the administration got Aaron C. Peterson confirmed in February.5 Judge Sharon L. Gleason, an Obama appointee who took office in 2012, is eligible for senior status. If she assumes it under a Senator Peltola, Peltola could keep the court from becoming all Trump appointees or negotiate a compromise nominee, perhaps more moderate than the administration’s preferred pick.

Iowa

In the Hawkeye State, Republican Ashley Hinson and Democrat Josh Turek are running for an open seat currently held by Republican Joni Ernst.6 Iowa has the closest race on the list in terms of polling, with Turek leading by one point.7 There are no vacancies or judges who are currently eligible, but there are two judges who will be eligible under the next senator. Both of these judges are in the Northern District of Iowa. With Judges Leonard T. Strand (Obama appointee) and C. J. Williams (Trump-1 appointee) in their early 60s, it is entirely possible that the next senator can see the entire district bench turnover with new active judges.

Maine

In Maine, Democrats are hoping to unseat five-term Senator Susan Collins with Troy Jackson.8 Similar to other competitive races, the Democratic candidate is leading by two points; however, several polls have Collins leading.9 The judicial stakes are relatively lower compared to other races in this article, with only one vacancy and no judge being eligible for senior status now or in the next six years. Of course, there is a chance of an unexpected retirement or death that could result in a vacancy. As for the one vacancy, this was the result of Obama appointee Nancy Torresen assuming senior status last year. There has yet to be an official nominee, which may be expected as the administration has worked very little in getting nominees confirmed in states with at least one Democratic senator, with notable exceptions in Michigan and Pennsylvania.4 Maine’s other senator is Democratic-caucusing Independent Angus King. King has voted seven times to confirm a judicial nominee under Trump’s second term and helped get a nominee confirmed in Trump’s first term. King has shown some willingness to work with the administration. Whether Jackson would is the open question.

Michigan

In the open Senate race in Michigan, Abdul El-Sayed (D) and Mike Rogers (R) are running to succeed retiring Senator Gary Peters (D).10 Polling shows a tight race according to FiftyPlusOne, with Rogers trailing El-Sayed by three points.11 There are no vacancies in the Eastern District or the Western District of Michigan, but there are seven judges eligible for senior status, with three more projected to reach eligibility under the next senator’s term. If Rogers wins, he will see up to about 53% turnover of the 19 active judges in the state absent retirements and deaths. This is significant for 10.1 million Michiganders as district judges are their first stop in the federal court system and are often the end of the line in lawsuits. Rogers can reshape the Eastern District, especially as 80% of all active judges there are Democratic appointees and the majority of judges who are and will be eligible are in this district and are Obama appointees. These Democratic-appointed judges have been confirmed with the support of the state’s Democratic delegation since 2008. If El-Sayed, who has been running more in line with complete opposition to President Trump, will likely not partake in any negotiations if a vacancy occurs in either district. This will leave a potential vacancy up until 2029 at the earliest.

New Hampshire

Like in Alaska and Maine, the Granite State has only one district and three active judgeships. Of those three judges, two (66.7%) will be eligible for senior status by January 3, 2033. One, Joseph N. Laplante, is a GWB appointee, while the other, Judge Landya B. McCafferty, is an Obama appointee. The Senate race will decide who will have a potential say in who replaces either or both of them: Republican John E. Sununu or Democrat Chris Pappas. Both are running to replace retiring Jeanne Shaheen (D).12 Should Pappas win, he may continue Shaheen’s bipartisan judicial streak or chart a new, harsher course in getting judicial nominees confirmed, especially in his state. In this new course, he may refuse to work with a Republican administration in filling future vacancies. If Sununu wins, he will have to work with New Hampshire’s other Democratic senator, Maggie Hassan, in filling them. Hassan, like Shaheen, also has a bipartisan streak.
