History

The 3rd congressional district has existed since 1837, having been organized from the at-large congressional district. It is centered on New Haven and its suburbs. The district comprises four-fifths of New Haven County, a small portion of Middlesex County, including most of Middletown, and most of Stratford and a small section of Shelton in Fairfield County.

New Haven and its surrounding suburbs are largely Democratic, making the district very Democratic in local and federal elections. Among districts statewide, only the 1st congressional district is considered more Democratic. Four Democratic strongholds, New Haven, Hamden, Middletown, and West Haven, comprise 40% of the total district population. Since 2000, Democratic presidential candidates have carried the district by a margin of 26 points. John Kerry, being the exception, still defeated George W. Bush by a comfortable 14 points. On the state level, moderate Republicans John G. Rowland and M. Jodi Rell have also carried the district.

Since 1933, Democrats have held the district for all but six terms (1943–45, 1947–49, 1953–59, 1981–83). Between 1972-1988, every Republican nominee for President carried the district, along with the state itself. In his sole run for a House seat, Joe Lieberman, lost the district to a Republican in 1980.
