**Senator Lisa Murkowski remains a registered Republican and continues to participate in Senate proceedings and endorsements under that affiliation as of September 2026.** She has introduced bipartisan legislation, including a measure with Sen. Alex Padilla on atmospheric river forecasting, while occasionally breaking with party lines on issues such as net neutrality rules and Iran-related war powers resolutions. Past speculation about potential caucusing changes or independent status has not materialized into any announced departure, and official records list her as the Republican incumbent with a term extending through 2029 and a 2028 reelection bid. These patterns of intra-party dissent without formal exit align with the market's strong "No" pricing, reflecting the absence of verifiable steps toward leaving the Republican conference by year's end.
