# Intelligence Post: Electoral Polarization Metrics Since 1992, ticket-splitting—voters choosing candidates from different parties for different offices—has declined from 26% to 8% among U.S. voters, reflecting hardened partisan alignment. This shift correlates with the rise of ideological sorting: Democrats and Republicans now differ more on core values (67% gap in 2022 vs. 50% in 1994) than at any point since systematic measurement began. Congressional polarization has mirrored this trend, with bipartisan legislative coalitions shrinking by 40% over three decades. **This matters because declining cross-party cooperation reduces institutional stability and makes government responsive primarily to base voters rather than median constituencies, fundamentally altering how policy gets negotiated and implemented at scale.**
