FRANK BELLOTTI IS 95, the kind of 95 you’d want to be if you live to be 95. Trim, tan, sharp of mind (but perhaps slower of gait), Bellotti joined me recently to record a CommonWealth Codcast. He is, I’m pretty sure, the oldest living former statewide office holder – he was lieutenant governor from 1963 to 1965, and attorney general for 12 years, from 1975 to 1987. Most people today probably remember him as the former AG, a role that was perfectly suited to this progressive libertarian whose personal discipline and rigorous preparation made him a formidable lawyer.
