She was the first woman to serve in both houses of the United States Congress, and the first woman to represent Maine in either. A Republican, she was among the first to criticize the tactics of Joseph McCarthy in her 1950 speech, "Declaration of Conscience".
William Dodd Hathaway was an American politician and lawyer from Maine. A member of the Democratic Party, he served as a United States senator for Maine from 1973 to 1979, as the U.S. representative for Maine's 2nd congressional district from 1965 to 1973, and as the commissioner of the Federal Maritime Commission from 1990 to 1999.

The Democratic Party increased its majority with a net gain of one seat from the Republican Party. The election cycle took place in the middle of President George H. W.

The Democrats picked up open seats in Kentucky and South Dakota, and defeated four incumbent senators: Gordon Allott of Colorado, J. Caleb Boggs of Delaware, Jack Miller of Iowa, and Margaret Chase Smith of Maine. The Republicans picked up open seats in New Mexico, North Carolina, and Oklahoma, and defeated one incumbent, William B. Spong Jr. of Virginia.

With divisions in the Democratic base over the Vietnam War, and with the traditional mid-term advantage of the party not holding the presidency, the Republicans took three Democratic seats, thereby breaking Democrats' 2/3rds supermajority. Despite Republican gains, the balance remained overwhelmingly in favor of the Democrats, who retained a 64–36 majority. Democrats were further reduced to 63–37, following the death of Robert F. Kennedy in June 1968.
