Well, since 1960, there have only been 2 Republican Governors prior to LePage. Jock McKernan, Olympia’s (second) husband, is a RINO and didn’t leave much of a mark (one problem for us is that Gov. LePage, although a Conservative, was friends with Olympia’s first husband, the late Peter Snowe, and he won’t actively oppose her reelection as a result). John Reed, who was Governor from 1959-67 (and is still alive, having turned 90 back on Jan 5th), was regarded as a moderate-to-liberal, but a pro-Vietnam hawk, although oddly lost reelection in 1966 despite the anti-Dem landslide. LBJ appointed him to the NTSB when he was defeated.
I probably have a higher opinion of the late Jim Longley, Sr., who served a single term in the ‘70s. He was a former Democrat who ran as an Independent (beating none other than George Mitchell). LePage is probably closer in spirit to Longley than either Reed or McKernan.
