For everyone counting on Social Security in retirement, the program’s most persistent congressional advocate just lost his seat.
John Larson of Connecticut, the top Democrat on the House Ways and Means Social Security Subcommittee, fell in a primary on Aug. 11, 2026, after 14 terms.
Former Hartford Mayor Luke Bronin captured about 54% of the vote in the Democratic primary, while Larson finished at roughly 33%, Roll Call reported.
Larson had reintroduced his signature bill, the Social Security 2100 Act, roughly six weeks before the primary, and the legislation will lose its lead House sponsor when his term ends in Jan. 2027.
His defeat comes at a precarious moment, with the program’s retirement trust fund projected to run out in the fourth quarter of 2032.
Larson becomes 7th House Democrat ousted in a 2026 primary
Bronin, the former Hartford mayor, framed his challenge around generational change.
He is a Navy veteran who served in Afghanistan and held multiple positions in the Obama administration before leading Hartford as mayor, as Luke Bronin for Congress showed.
Larson became the seventh House Democrat to lose a primary in 2026, swept up in a broader push to replace longtime incumbents with younger candidates.
What the Social Security 2100 Act proposed to change before Larson’s exit
Larson reintroduced the Social Security 2100 Act on June 29, 2026, and Senator Richard Blumenthal of Connecticut filed a Senate version on July 21, 2026.
The bill proposed an across-the-board benefit increase and a shift in how cost-of-living adjustments are calculated, using a senior-specific inflation index.

“Although the Social Security 2100 Act is unlikely to pass in the current Congress, it should. The bill is the gold standard for Social Security reform and accomplishes the majority of changes older Americans want to see for the program,” Shannon Benton, executive director of The Senior Citizens League, said in a statement.
The legislation-tracking site GovTrack gave the bill a 0% chance of becoming law even before Larson’s defeat, underscoring the resistance Social Security reform faces.
Connecticut retirees stand to lose the most if the trust fund depletes
Larson’s home state would absorb the steepest per-retiree benefit cut in the country under a depletion scenario, adding a layer of irony to his departure.
Connecticut beneficiaries face an average monthly benefit reduction of $556, the Committee for a Responsible Federal Budget found in its June 2026 state-by-state analysis.
The national average monthly cut would total $500, an amount that exceeds what the typical retired household spends on groceries each month, the CRFB found.

Marc Goldwein, Senior Vice President and Senior Policy Director at the Committee for a Responsible Federal Budget, explained in a June 2026 CNBC interview that the CRFB’s state-by-state analysis reflects the outcome if Congress simply does nothing, although lawmakers have other options available to them.
What we’re showing is what would happen if there’s no changes to the law or to policy
About 63 million Americans, roughly one in five, would be directly affected under the organization’s 24% across-the-board cut scenario, the CRFB found.
For retirees who depend on Social Security for most of their income, a cut of that scale would leave few financial alternatives, the CRFB noted.
The 2032 depletion deadline and who will be serving when it arrives
Senators elected this November will serve through early 2033, placing them directly in office during the projected depletion date and any emergency legislative response.
House members elected in 2026 will finish their terms in January 2029, three full years before the trust fund hits zero.
Two recent federal laws have pushed the depletion date closer than the prior year’s projection had anticipated, the 2026 Trustees Report confirmed.
Two 2025 laws, the Social Security Fairness Act and the One Big Beautiful Bill Act, together pulled the depletion date closer by increasing outlays and reducing revenue
“…With Social Security reaching insolvency in just a few short years, and a 22% cut in benefits looming because of inaction, time is running out to address a critical program relied upon by 70 million Americans…,” Maya MacGuineas, president of the Committee for a Responsible Federal Budget, said in June.
What Larson’s exit means for the benefit check you are projecting
Larson’s departure does not change the math of depletion, but it removes a concentrated pressure point on Congress to act before the fund runs dry.
Benton noted that lawmakers will almost certainly need to pass a solvency bill in coming years, calling the deadline a rare chance to strengthen benefits.
The Social Security Administration maintains projected benefit figures for every worker in its My Social Security account system. CRFB’s analysis models a 22% reduction applied to those figures as the baseline depletion scenario
Whether the next Congress and the next presidential administration act before the fourth quarter of 2032 will determine whether current workers’ projected benefits arrive intact, a question voters will weigh in November and again in 2028.
