I want to know the answer to the following question:
What party did Brennan belong to?
All the background I'm provided with is that "In selecting a Chief Justice, Eisenhower looked for an experienced jurist who could appeal to liberals in the party as well as law-and-order conservatives, noting privately that Warren "represents the kind of political, economic, and social thinking that I believe we need on the Supreme Court ...". Is that enough to answer the question?
Answer: no
