Context: In 1970, Kerry had considered running for Congress in the Democratic primary against hawkish Democrat Philip J. Philbin of Massachusetts's 3rd congressional district, but deferred in favour of Robert Drinan, a Jesuit priest and anti-war activist, who went on to defeat Philbin. In February 1972, Kerry's wife bought a house in Worcester, with Kerry intending to run against the 4th district's ageing thirteen-term incumbent Democrat, Harold Donohue. The couple never moved in. After Republican Congressman F. Bradford Morse of the neighbouring 5th district announced his retirement and then resignation to become Under-Secretary-General for Political and General Assembly Affairs at the United Nations. The couple instead rented an apartment in Lowell, so that Kerry could run to succeed him.
