I want to know the answer to the following question:
Why did President Levin believe there were so many Yale alumni presidential candidates?
All the background I'm provided with is that "Yale President Richard Levin attributes the run to Yale’s focus on creating "a laboratory for future leaders," an institutional priority that began during the tenure of Yale Presidents Alfred Whitney Griswold and Kingman Brewster.". Is that enough to answer the question?
Answer: yes
