Prior to the ratification of theSeventeenth Amendment in 1913, senators were elected by theConnecticut General Assembly.[3] Each state elects varying numbers of members of the House, depending on population, to two-year terms.[4] Connecticut has sent five members to the House in each congressional delegation since the2000 United States census.[5]

She is the longest-serving House member in Connecticut history, and the second longest-serving member of Congress from Connecticut, behindChris Dodd, who served 36 years combined in the House and Senate.[9] Dodd is also Connecticut's longest-serving senator.[10]
