John Larson
Larson’s market fell from about 67%-68% to 30% in the last day, following Luke Bronin’s convention win and a fresh wave of endorsements. That keeps the CT-01 Democratic primary highly tradable and suggests the market is repricing Larson as a clear underdog.

Notable personal detailsJohn Barry Larson is a U.S. Representative for Connecticut’s 1st Congressional District, first elected to Congress in 1998 and serving since 1999. Before Congress, he served in the Connecticut State Senate and was Senate President pro tempore (1987–1995). He previously worked as a high school history teacher and coach, and has been active in Democratic politics in Connecticut for decades.
Supports measures that protect middle-class taxpayers and oppose large tax cuts for the ultra-wealthy and corporations, while backing tax credits and program expansions that aid families and workers. Serves on the House Ways and Means Committee and has sponsored or supported amendments and legislation intended to shield middle-income taxpayers and extend targeted tax relief (for example, ACA premium tax credits and child-related supports).
Supports expanding public coverage through a Medicare-based public option (described as “Medicare for All Who Want It”) and policies to increase access and affordability rather than eliminating private insurance. Advocates targeted measures such as protections for people with preexisting conditions and efforts to reduce drug costs.
Supports protections for immigrants and asylum access while backing bipartisan reforms and oversight of immigration enforcement; opposes racial profiling and ICE actions near polling places and has supported resettlement for vulnerable allies. Positions combine humanitarian protections with support for negotiated/enforcement reforms.
Supports protecting and restoring nationwide access to abortion and reproductive health care, including sponsoring federal legislation to codify abortion rights and guarantee abortion services through federal programs. Frames reproductive rights as fundamental health care and has introduced/co-sponsored bills to restore Roe-era protections and ensure abortion access for veterans.
Supports addressing climate change through clean-energy investment, industry transition policies, and market-based measures such as carbon pricing; advocates for fuel-cell and hydrogen technology and federal funding for renewable energy and infrastructure. Endorses climate solutions and modernizing the economy while reducing emissions rather than rejecting transitional fossil-fuel use outright.
Supports enhanced background checks, closing background-check loopholes, state red flag laws/funding, and restrictions on assault weapons and high-capacity magazines; has sponsored/advocated for legislation to limit access to assault weapons and related financing. Has voted in favor of federal background-check legislation.
Larson’s market fell from about 67%-68% to 30% in the last day, following Luke Bronin’s convention win and a fresh wave of endorsements. That keeps the CT-01 Democratic primary highly tradable and suggests the market is repricing Larson as a clear underdog.
Larson’s CT-01 primary odds have bounced back from the mid-30s to about 50% even after Luke Bronin’s convention win, keeping the market in a volatile two-way repricing that traders may want to monitor for another leader flip.
The latest poll has John Larson ahead by 26.0 points, but Luke Bronin is leading the odds for the Connecticut-01 Democratic nomination.
John Larson is in the news because he is facing a Democratic primary challenge in Connecticut's 1st Congressional District. Recent coverage says Luke Bronin won the party endorsement and is being presented as the change candidate, while Larson is being backed by supporters who point to his record on labor, healthcare, transportation, and Social Security. The race is still active, and the reports do not give any final election result or polling data.
