Britain’s Labour Party and its far-left leader, Jeremy Corbyn, suffered a historic defeat in yesterday’s general election. Although there are massive differences between Corbyn’s brand of socialism and our own Democratic Party, left-leaning liberals such as Elizabeth Warren and Bernie Sanders would be wise to pay attention.

Corbyn has spent much of the past four years as the party leader pushing Labour further and further to the left, advocating for the “un-privatization” of municipal energy companies and railways, among other things. Corbyn wanted nothing short of a complete economic transformation. He even referred to his own platform as “radical.” And his party’s unexpected albeit modest gains in the 2017 British election suggested that he might just achieve it.
