U.S. Representative John Larson of Connecticut was defeated in Tuesday's Democratic primary by former Hartford Mayor Luke Bronin, ending his bid for the November general election. Larson, a senior member of the House Ways and Means Social Security Subcommittee, has long advocated for the "Social Security 2100 Act" to expand Social Security benefits and extend its solvency. His defeat could impact future efforts to address the projected depletion of the Social Security trust fund in 2032.
