Here’s what Democrats want to do now.
Democrats are escalating their battle over the U.S. Supreme Court, promoting a series of proposals that could dramatically change the nation’s highest court and potentially reshape the conservative majority influenced by President Donald Trump’s judicial appointments.
With the November midterm elections approaching, Democratic lawmakers are increasingly focusing on Supreme Court reform as a major political issue. Their proposals include expanding the court from nine to 13 justices, establishing 18-year terms for active Supreme Court service and imposing new transparency and ethics requirements.
Republicans are pushing back, arguing that some of these proposals could weaken judicial independence and allow politicians to restructure the Supreme Court whenever they become unhappy with its ideological direction.
The disagreement is shaping up to become an important election issue with potentially enormous consequences for the future of the federal judiciary.
Democrats Push to Expand Supreme Court to 13 Justices
Perhaps the most controversial proposal would increase the Supreme Court from nine justices to 13.
The effort builds on legislation previously introduced by Democratic lawmakers, including Sen. Ed Markey of Massachusetts and Rep. Hank Johnson of Georgia.
Supporters argue that 13 Supreme Court seats would correspond with the nation’s 13 federal appellate circuits.
Republicans see the proposal very differently.
They have repeatedly described Supreme Court expansion as “court-packing,” warning that adding seats could allow whichever political party controls Washington to alter the ideological balance of the court.
That concern carries particular significance during Trump’s presidency.
Trump appointed three Supreme Court justices during his first term — Neil Gorsuch, Brett Kavanaugh and Amy Coney Barrett — helping establish the court’s current 6-3 conservative majority.
Adding four seats could provide a future Democratic president with an opportunity to substantially change that balance, assuming Democrats also controlled enough Senate votes to confirm new nominees.
For conservative voters, that possibility makes the Supreme Court debate about much more than congressional procedure.
It could determine the ideological direction of the nation’s highest court for decades.
Trump’s Supreme Court Legacy Is at the Center of the Fight
Trump’s impact on the Supreme Court remains one of the most consequential parts of his political legacy.
His three appointments helped create a conservative majority that has played a central role in major legal battles involving abortion, gun rights, religious liberty, federal regulatory authority and presidential power.
Democrats have sharply criticized many decisions from the conservative majority and are increasingly discussing structural changes to the institution.
Republicans, meanwhile, argue that changing the size of the court because of dissatisfaction with its rulings could establish a dangerous precedent.
If one party expands the court after gaining power, critics warn that the opposing party could simply add additional seats the next time it controls Washington.
That possibility has made Supreme Court expansion one of the most contentious judicial proposals being debated in the country.
Democrats Propose 18-Year Supreme Court Terms
Another major Democratic proposal focuses on how long justices actively serve on the Supreme Court.
Sen. Sheldon Whitehouse of Rhode Island is among the leading supporters of legislation that would establish 18-year periods of active service on the court’s full docket.
Whitehouse joined Democratic Sens. Cory Booker of New Jersey, Richard Blumenthal of Connecticut and Alex Padilla of California in reintroducing the Supreme Court Biennial Appointments and Term Limits Act.
Under the proposal, appointments would be staggered so that a new justice could regularly join the court approximately every two years.
After completing 18 years of active service, justices would transition into a senior role and participate only in a limited category of cases.
Supporters argue the system could make Supreme Court vacancies more predictable and prevent individual presidents from having an unusually large influence simply because several vacancies occur while they are in office.
Opponents question whether Congress should fundamentally alter a system built around lifetime judicial appointments.
Senate Judiciary Committee Chairman Chuck Grassley of Iowa has opposed the 18-year approach and warned about its potential effect on judicial independence.
Why Lifetime Supreme Court Appointments Matter
The Constitution gives federal judges life tenure during “good Behaviour,” a system intended to help insulate the judiciary from day-to-day political pressure.
That independence is one reason Supreme Court appointments carry such enormous consequences.
Presidents may leave office after four or eight years, while their judicial nominees can continue serving for decades.
Trump’s appointments demonstrate exactly why Supreme Court nominations have become so politically significant.
The debate over 18-year active terms therefore raises a broader constitutional question: How much authority should Congress have to restructure the practical operation of lifetime Supreme Court service?
Any sweeping change could trigger a major legal challenge.
Democrats Also Target the Supreme Court’s ‘Shadow Docket’
Court expansion and term limits aren’t the only proposals gaining Democratic support.
Lawmakers are also targeting the Supreme Court’s emergency decision-making process, frequently referred to as the “shadow docket.”
The process allows the court to handle urgent cases on an accelerated schedule, sometimes without the extensive briefing and oral arguments associated with ordinary Supreme Court cases.
Democratic lawmakers want greater transparency surrounding those decisions.
The Shadow Docket Sunlight Act, backed by Sens. Dick Durbin and Richard Blumenthal along with Rep. Deborah Ross, would require additional written explanations and information about how justices voted on certain emergency orders.
Rep. Jamie Raskin of Maryland has also promoted legislation addressing the court’s emergency procedures.
Democrats supporting these changes argue that Americans deserve to understand the reasoning behind consequential Supreme Court decisions.
Republicans and other critics of congressional intervention are likely to focus on a different concern: preserving the Supreme Court’s independence from political pressure coming from Capitol Hill.
Supreme Court Ethics Become Another Political Battleground
Democratic lawmakers are also seeking stronger ethics requirements for Supreme Court justices.
Ethics questions have become another major front in Washington’s ongoing battle over the judiciary.
Supporters say stronger rules could increase public confidence in the court and create clearer standards for justices.
But conservatives will be watching closely to determine whether proposed ethics legislation establishes neutral standards or gives Congress additional leverage over a separate branch of government.
That distinction could become increasingly important as the political battle over the Supreme Court intensifies.
Republicans Want to Permanently Keep Nine Justices
Republicans are advancing their own proposal designed to prevent future court expansion.
House Judiciary Committee Chairman Jim Jordan of Ohio has backed a constitutional amendment establishing nine Supreme Court justices.
Grassley has supported the same general idea.
Such an amendment would make it considerably harder for a future congressional majority to expand the Supreme Court for political reasons.
The Republican proposal effectively turns the Democratic expansion campaign on its head.
Instead of debating whether four seats should be added, Republicans want to make nine seats a permanent constitutional limit.
Why Nine Supreme Court Justices Became the Standard
The Constitution does not explicitly require the Supreme Court to contain nine justices.
Congress has historically determined the size of the court, and the number changed several times during the country’s early history.
The Supreme Court has consisted of nine justices since the 19th century, making the current structure familiar to generations of Americans.
That history means the argument over 13 justices is not simply about whether Congress possesses power over the court’s size.
The larger political question is whether lawmakers should exercise that power specifically because they object to the current court’s ideological composition.
Republicans say doing so could politicize the judiciary even further.
Democrats supporting expansion argue that substantial reform is necessary to restore confidence in the institution.
Could Democrats Actually Expand the Supreme Court?
Not anytime soon.
Republican control of the Senate creates a major barrier to Democratic Supreme Court legislation during the current Congress.
President Trump would also stand between Democrats and enactment of legislation designed to restructure the court.
As a result, the immediate significance of these proposals is primarily political.
The 2026 midterm elections could determine whether Democrats gain enough congressional power to advance their Supreme Court agenda.
The 2028 presidential election could be even more important.
If Democrats eventually controlled the House, Senate and White House simultaneously, proposals currently considered unlikely could receive much more serious consideration.
Senate procedural rules would remain another substantial obstacle, however, particularly for legislation that could face a filibuster.
2026 Midterms Raise the Stakes
That makes November’s congressional elections especially important.
Democrats are increasingly presenting Supreme Court reform as part of a broader argument about the direction of the judiciary.
Republicans are presenting themselves as defenders of the nine-member court and warning voters about what Democratic control could mean for Trump’s judicial legacy.
The outcome could affect far more than a single piece of legislation.
Control of the Senate determines who confirms future Supreme Court nominees and hundreds of judges throughout the federal court system.
A Senate majority could therefore shape the judiciary even without changing the Supreme Court’s size.
What Would Happen If Another Supreme Court Seat Opens?
An unexpected vacancy could immediately transform the political landscape.
Every Supreme Court nomination has the potential to affect American law for a generation, and the current ideological divide makes the next vacancy particularly significant.
Trump’s ability to nominate another justice would give Republicans an opportunity to reinforce the court’s conservative wing.
A future Democratic president would have the opposite opportunity.
That reality explains why both parties are placing increasing attention on the judiciary as voters prepare for another major election.
Conservatives Face a Long-Term Supreme Court Battle
For conservative Americans, especially voters who supported Trump partly because of his judicial appointments, the latest Democratic proposals deserve attention.
The issue is not simply whether Democrats can pass these bills today.
They currently face formidable obstacles.
The more significant question is whether these proposals are becoming part of the Democratic Party’s long-term governing agenda.
Court expansion, term limits, ethics legislation and changes to emergency Supreme Court procedures represent different approaches, but all would alter aspects of the institution as it currently operates.
Republicans are responding by trying to preserve nine seats and emphasizing judicial independence.
The Bottom Line
The battle over the Supreme Court is rapidly becoming another major dividing line between Democrats and Republicans.
Democrats frustrated with the conservative majority are promoting proposals that could expand the court, limit active service to 18 years and impose additional transparency and ethics requirements.
Republicans want to maintain the nine-member court and warn that restructuring it for political reasons could create a cycle in which each party changes the institution after gaining power.
President Trump’s three Supreme Court appointments remain at the heart of the debate because they helped establish a conservative majority whose decisions could influence American law for decades.
Democrats currently lack a realistic path to enact their most ambitious proposals. But elections can change the balance of power quickly in Washington.
That makes the 2026 midterms — and eventually the 2028 presidential election — potentially decisive moments in the long-running fight over the future of the U.S. Supreme Court.
For voters concerned about constitutional government, judicial independence, presidential power and the future direction of the country, this is one political battle that is unlikely to disappear anytime soon.
