I want to know the answer to the following question:
What political party was Morse in?
All the background I'm provided with is that "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.". Is that enough to answer the question?
