There are a lot of similarities and differences: They are both men over 65 but England’s Jeremy Corbyn is a traditional Labourite leftist while Bernie Sanders is an all-American left-leaning Democratic populist. But both campaigns earned their descriptions as political earthquakes. They both came out of nowhere and are now leaders of  significant new movements. Today’s British Labour Party is a far cry from the Clinton-style of former leader Tony Blair. And Sanders is not more of the same corporate-coddling Democrats. There are many parallels and many differences, but according to our guest in London, editor at large for The Nation DD Guttenplan, they both signal that something new is happening.
