 Hartford casts large pluralities for the Democratic candidate in all races, and the former mill towns which surround the capital, such as East Hartford and Middletown, have largely retained their ethnic Democratic heritage.Congressman John B. Larson, the former President "pro tempore" of the Connecticut Senate from East Hartford, has represented the 1st district since 1999.He succeeded Barbara B. Kennelly, who had unsuccessfully challenged Governor John G. Rowland during that election cycle.
