Dylan is an artist not an ideologue, arguably America's greatest troubadour. For a taste of Left-Right polarity in Dylan's work already in the 1960s compare Subterranean Homesick Blues with Father of Night. The Weatherman faction of the SDS got its name from the line, "It don't take a weatherman to know which way the wind blows" from the former. It is worth noting that Dylan's farewell to ideology came early, in 1964, in My Back Pages, thus a year before "Subterranean Homesick Blues." If you can't stand Dylan's voice, give a listen to this high-powered version of "My Back Pages" featuring Roger McGuinn, Eric Clapton, George Harrison, Tom Petty, Neil Young, et al.
"Ah, but I was so much older then, I'm younger than that now."
