    U.S. House · Connecticut – District 1

    Lost 2026 primary to Luke Bronin

    $246,843

    in backing from AIPAC, UDP & allied PACs

    $245K via AIPAC PAC ($222K in earmarked donations from AIPAC’s donors that it passed on, $22.9K from the PAC itself) + $2,000 from other PACs

    • Voting score 59% (19 votes, average of 3 areas)
    • +$147K donor network
    • Second score (immigration & Wall Street) 100%
    • Other pro-Israel PACs: DMFI PAC $2,000
    59%Voting score on Israel, war powers & civil liberties: the three areas averaged equally; 100% = the scored vote every time
    100%Second score: immigration & Wall Street
    $147Kgiven directly by 60 people who also gave to AIPAC PAC or UDP
    4%of campaign money from small donors

    How the 59% is calculated: the equal-weight average of Israel & Gaza 43% (7 votes), Speech & civil liberties 33% (9 votes), War powers 100% (3 votes). Higher means more often casting the scored vote: against military aid to Israel without new conditions and against ICC sanctions, for blocking arms sales, for requiring Congress to authorize war, and for civil liberties. Each area (Israel & Gaza, war powers, speech & civil liberties) counts equally, so the score is an average of areas, not the share of all listed votes.
