Republican caricatures of Al Gore notwithstanding, the former vice president was never a stereotypical woolly environmentalist. A practicing Southern Baptist, Gore attended divinity school and, though he opposed the Vietnam War, he enlisted in the military rather than protesting it. Gore rose in the 1980s as a moderate “New Democrat,” who was friendly to business, hawkish on foreign policy and, yes, excited about the possibilities of technological innovation. As vice president, he set about the earnest work of “reinventing government” to make it more efficient.

Gore’s attraction to environmentalism, much like that of New York City Mayor Mike Bloomberg’s, is that of a serious wonk, not a dirty hippie who finds water conservation a convenient excuse not to bathe.

And so it is actually quite remarkable that, as Forbes reported in this week’s issue and The Washington Post confirmed with a source close to Gore on Monday, he has gone vegan. Forbes merely tossed in a throwaway line referring to Gore as “newly vegan,” in a story about investors looking at ways of replacing eggs with plant-based formulas. The Post was unable to get any further details beyond confirmation from an unnamed Gore associate.
