The guy was funny when Hector was a pup. I can remember seeing him do all six or eight different Boston accents plus running through all the other local dialects throughout New England. He had an ear for it and it was really funny, especially if you knew NE's regions before TV newscasters flattened America's dialects.
Other than that, he was a plain vanilla, boiler-plate lefty all his life, and his so-called "anger" was more the grating whine of a political loser.
