I want to know the answer to the following question:
In what year did Bob Graham become Governor of Florida?
All the background I'm provided with is that "And during his two terms (1979–1987) as Florida's Governor, Bob Graham, although a strong death penalty supporter who had overseen the first post-Furman involuntary execution as well as 15 others, agreed to commute the sentences of six people on the grounds of "possible innocence" or "disproportionality."". Is that enough to answer the question?
