I want to know the answer to the following question:
Which of Northwestern's alumni is notable for becoming a U.S. Senator and presidential candidate?
All the background I'm provided with is that "Among Northwestern's more notable alumni are U.S. Senator and presidential candidate George McGovern, Nobel Prize–winning economist George J. Stigler, Nobel Prize–winning novelist Saul Bellow, Pulitzer Prize–winning composer and diarist Ned Rorem, the much-decorated composer Howard Hanson, Deputy Prime Minister of Turkey Ali Babacan, the historian and novelist Wilma Dykeman, and the founder of the presidential prayer breakfast Abraham Vereide.". Is that enough to answer the question?
Answer: yes
