I want to know the answer to the following question:
Why did Gaddis Smith believe John Kerry led Yale's Political Union Liberal Party?
All the background I'm provided with is that "Yale historian Gaddis Smith notes "an ethos of organized activity" at Yale during the 20th century that led John Kerry to lead the Yale Political Union's Liberal Party, George Pataki the Conservative Party, and Joseph Lieberman to manage the Yale Daily News.". Is that enough to answer the question?
