Poll shows 64% of Americans support Keep Nine amendment to maintain nine Supreme Court justices

A new poll released on October 5, 2026 found that nearly 64 percent of respondents support a constitutional amendment, called Keep Nine, that would require the United States Supreme Court to be composed of nine justices.

The finding matters because it shows a strong national preference for keeping the Court at its historic size just as Democratic leaders have signaled plans to expand the bench if they regain power in upcoming elections.

Among party lines, 46 percent of Democrats said they would back the amendment, while 54 percent of independents expressed support. Only about 18 percent of all respondents opposed the measure, creating a more than three‑to‑one margin of favorability.

The poll’s own analysis noted that the public’s backing of a nine‑justice Court dwarfs opposition, suggesting that any effort to add justices could face significant voter resistance.

"The public favoring keeping the court at nine justices by a more than 3‑1 margin," the poll reported, underscoring a clear consensus that many voters view the current Court size as appropriate for the nation’s judicial system.

Democratic lawmakers have publicly stated they would pursue court expansion as part of broader judicial reforms if they secure a congressional majority. The new data indicates that such a proposal would run counter to the expressed wishes of a sizable portion of the electorate, including a notable share of Democratic voters.

Lawmakers and advocacy groups are likely to cite the poll as evidence in debates over any constitutional amendment process, which would require a two‑thirds vote in both chambers of Congress and ratification by three‑fourths of the states. The coming months may see intensified campaigning on both sides of the issue ahead of the 2028 election cycle.
