House Democrats defeated a Republican-backed constitutional amendment that would have permanently fixed the Supreme Court at nine seats, a vote that Republicans say exposes the left's willingness to pack the bench for political advantage.
The measure failed 212, 206 on the House floor, falling far short of the two-thirds supermajority a constitutional amendment requires. Only one Democrat, Rep. Don Davis of North Carolina, crossed party lines to vote with Republicans. Every other Democrat present voted no, killing an amendment that would have done nothing more than enshrine a court structure the country has maintained since 1869.
Speaker Mike Johnson, who fast-tracked the legislation under a suspension-of-the-rules procedure, framed the vote as a trap designed to force Democrats onto the record. That procedural shortcut, which bypasses committee and limits debate, also raises the passage threshold from a simple majority to two-thirds, meaning Republicans knew the amendment would likely fail. The point was to make Democrats say so out loud.
"We will have them put their money where their mouth is," Johnson told reporters ahead of the vote.
Johnson aimed his sharpest remarks at the Democratic Socialists of America, whose official platform calls for abolishing the Supreme Court entirely and replacing it with a judiciary subordinate to Congress. He suggested that only a handful of House Democrats were willing to distance themselves from that position.
"There's a couple of Democrats here in the House who have suggested that they're not on board with the Democratic Socialists of America. Just a few," Johnson said. "They're going to get a chance to show us."
The vote showed that almost none of them took the chance. Davis stood alone.
Rep. Andy Biggs of Arizona, who led the amendment effort, argued that the measure was necessary to insulate the high court from political pressure. As the New York Post reported, Biggs had been making the case for months:
"How can the Supreme Court protect Americans from government overreach if the same government can pack the court whenever it dislikes a ruling?"
Biggs made that argument during a discussion about the amendment in July, weeks before the floor vote. Fox News reported that Biggs also warned that once court expansion begins, the bench "stops being an independent check on government power" and "becomes another political institution controlled by whoever happens to hold the majority."
Republicans did not have to speculate about Democratic intentions. Former Vice President Kamala Harris said at an event in July that the party should revisit expanding the bench.
"We need to revisit the point of expanding the court to 13 justices like we have 13 district courts."
Rep. Jim Clyburn of South Carolina echoed that number on NBC's "Meet the Press" over the weekend before the vote, calling "a baker's dozen" a good number for the court. Democrats have pushed legislation to reshape the Supreme Court for months, and the Harris and Clyburn remarks gave Republicans a concrete target to aim at.
The nine-justice structure has held since 1869. Congress set the number by statute, not by constitutional mandate, which means a future Congress could expand the court through ordinary legislation, provided it could clear the Senate's 60-vote filibuster threshold. The amendment Republicans brought forward would have closed that door permanently by writing the nine-seat cap into the Constitution itself.
Democrats chose to leave that door open.
Rep. Jamie Raskin of Maryland dismissed the amendment as election-year theater. As Newsmax reported, Raskin called it "another partisan power grab by MAGA" and accused Republicans of fearing November's results "as their policies have brought us nothing but war, inflation, corruption, lawlessness and a $40 trillion debt."
Rep. Mary Gay Scanlon, a Pennsylvania Democrat, offered a more direct objection to the amendment's substance. She said it would be "a grave mistake to dictate how many justices should sit on the Supreme Court in perpetuity, and thereby lock in for a generation or more a right-wing majority."
That argument concedes the point Republicans were trying to make. Scanlon did not object to nine justices as a number. She objected to nine justices as a ceiling, because the current conservative 6, 3 majority, built largely through appointments during the Trump administration, would remain intact. The goal is not stability. The goal is the option to change the rules later, when the political math shifts.
Republicans have faced their own political fractures in recent months, but on this vote the party was largely unified. The 212, 206 tally, with Republicans holding 218 seats to Democrats' 214, suggests a small number of absences or abstentions on the Republican side, but the overwhelming majority of the GOP caucus voted yes.
The idea of expanding the Supreme Court is not new. Franklin D. Roosevelt threatened to pack the bench in the 1930s after the court struck down key New Deal programs. The backlash was fierce, even from members of his own party, and the plan collapsed. For decades afterward, court-packing was treated as a settled bad idea across the political spectrum.
That consensus has eroded. Democratic leaders are now openly discussing expansion, and the party's progressive wing, aligned with the DSA, has gone further, calling for the court's abolition. The DSA's official program envisions a judiciary subordinate to Congress, a structure that would strip the bench of its independence entirely.
Previous efforts to constitutionally cap the court have also failed. Breitbart reported on a similar 2022 vote in which 218 Democrats blocked a Republican amendment, H.J. Res. 11, introduced by Rep. Dusty Johnson of South Dakota, that would have accomplished the same goal. Johnson warned at the time: "Where does it end? Y'all take it to the 13, a few years later we take it to 15, you can take it to 17 after that... This leads to madness."
Four years later, Democrats gave the same answer. No.
The Supreme Court has been a central flashpoint in American politics for years, with major rulings on executive power and constitutional questions keeping the judiciary at the center of partisan battles. Both parties understand that the court's composition shapes policy for a generation. The difference is that only one party refuses to guarantee the structure that has held for more than 150 years.
Congressional Democrats have also faced internal upheaval from their own primary voters, who have pushed the caucus further left on judicial issues and institutional reform. The pressure to embrace court expansion comes not from the political center but from the party's activist base, the same base aligned with the DSA's vision of a weakened, subordinate judiciary.
Don Davis's lonely crossover vote underscores how little room remains for dissent inside the Democratic caucus on this issue. Davis, who represents a competitive North Carolina district, had reason to break ranks. The rest of his colleagues did not, or chose not to.
Johnson framed the vote as a simple test: Do you believe the Supreme Court should stay at nine justices, yes or no? Democrats answered with near-unanimity. They do not want to enshrine the current structure. They want the flexibility to change it.
The amendment's failure carries no immediate legal consequence. The Supreme Court remains at nine seats. But the vote creates a clear record. When Democrats say they are not interested in court-packing, 205 of their House members just voted against the one measure that would have made that promise permanent.
A party that refuses to lock in a 157-year-old institutional norm is not defending the status quo. It is keeping its options open, and voters deserve to know what those options are.
