For decades, the gravitational center of the U.S. Supreme Court could be pinpointed to a single seat. Justice Anthony Kennedy famously occupied that role\u2014casting pivotal votes on same-sex marriage, affirmative action, campaign finance, and capital punishment. His jurisprudence wasn\u2019t always consistent, but it was often decisive. With his retirement, and the appointments of Justices Gorsuch, Kavanaugh, and Barrett, the Court adopted a solid 6\u20133 conservative majority. Many observers concluded the swing vote had vanished\u2014an artifact of a bygone era of ideological balance.<\/p>\n

But the story doesn\u2019t end there.<\/p>\n

In this article, I analyze all 104 closely divided Supreme Court decisions from 2020 onward\u2014the Barrett era\u2014each decided by either a 5\u20134 or 6\u20133 vote. The question: does a swing justice still exist? If so, who fills that role? And just as critically\u2014does swing behavior depend on the\u00a0kind<\/em>\u00a0of case?<\/p>\n

To answer this, I combined full-text analysis of opinions with voting data, legal metadata, and case structure. Using natural language processing alongside doctrinal tagging from the\u00a0U.S. Supreme Court Database<\/a>\u00a0(such as cited constitutional amendments or statutory bases), I clustered decisions not just by linguistic similarity, but by\u00a0legal substance<\/em>. These fused clusters revealed distinct issue areas\u2014ranging from Fourth Amendment policing to statutory procedure to ambiguous constitutional rights\u2014each with its own swing dynamics.<\/p>\n

With the six conservative justice majority at least two of these justices need to pivot to vote with the three more liberal justices to swing a vote. This means that by definition the notion of a true swing justice is contested. This also means to ascertain a swing justice or justices we need to have a broader perspective than was previously accepted when there were four liberal justices, four conservative justices, and Kennedy who primarily voted along with the conservatives but was most likely to be the swing vote, especially in high profile civil liberties decisions.<\/p>\n

What emerged from this analysis wasn\u2019t a Kennedy-style centrist. It was a fragmented map of ideological flexibility. Chief Justice Roberts and Justice Kavanaugh swing frequently, but selectively. Justice Barrett\u2019s influence, once assumed to be rigidly conservative, is quietly increasing\u2014particularly in cases touching on procedural fairness, personal liberty, or the limits of government power.<\/p>\n

The result is not one swing vote, but a constellation of issue-specific coalitions. In some areas, the conservative bloc holds firm. In others\u2014especially where dignity, restraint, or individual autonomy are in play\u2014the ideological lines begin to fracture.<\/p>\n

This article charts that evolving terrain: not a search for a single median justice, but a deeper attempt to understand how judicial moderation now depends on doctrine, institutional pressure, and legal context.<\/p>\n

The Dataset and Methodology<\/strong><\/h3>\n

To analyze contemporary swing voting on the U.S. Supreme Court, I assembled a dataset of 104 decisions from the terms beginning in 2020\u2014the period since Justice Amy Coney Barrett joined the Court. Each case was either a 5\u20134 or 6\u20133 decision, representing the narrowest outcomes where a single vote could have changed the result.<\/p>\n

Each entry in the dataset includes:<\/p>\n
