If Theresa May wins her expected victory in June’s British elections it will represent the latest evidence of a sweeping international trend: the utter collapse of the old left.

Britain’s Labour Party dominated the United Kingdom for 13 years under Tony Blair and Gordon Brown, but with radical leader Jeremy Corbin, it’s struggled for traction and relevance. The same thing happened in France, where the candidate of the long-dominant Socialists finished a dismal 5th in recent elections.

In Germany, center right Chancellor Angela Merkel has already ruled for 12 years and is heavily favored to capture another term in September. And in Israel, the leftist Labor Party that held power for the nation’s first 29 years, now commands only 16 percent of their Parliament; Prime Minister Bibi Netanyahu faces more formidable competition from fellow leaders on the right.

In America, as Bernie Sanders, Elizabeth Warren and other hard-liners drag Democrats leftward, the nation’s oldest political party faces much the same fate.
