The work of unraveling President Barack Obama’s legacy is underway, but even if the Trump administration and a Republican Congress reverse every last law and regulation, they won’t be able to touch the core of it. Obama’s enduring legacy will be as a cultural symbol, the first African-American president who represented a current of social change in the country and reflected the values and attitudes of the progressive elite. He will be remembered - and revered - by his admirers as his generation’s JFK. The standards here are largely stylistic, and Obama checks nearly every box: He was a young president; a photogenic man with a good-looking family; a symbol of generational change; an orator given to flights of inspiring rhetoric; if not a wit exactly, a facile talker with a taste for mocking the other side.
