Leftist parties in Europe are facing declining membership, electoral routs, and a general malaise:

The sick list is headed by Britain’s Labour Party, where veteran radical Jeremy Corbyn last week easily won a leadership challenge by centrist MPs angry at his part in the shock Brexit vote.

But political analysts say the venerable party — founded in 1900 — faces electoral oblivion despite his victory.

Its dismal standing in the opinion polls is mirrored across Europe.

As with Labour, Spain’s Socialist Party is in the grip of a fratricidal war over the performance of its leader, Pedro Sanchez, at a time of national crisis.

In Germany, the Social Democratic Party has lost half its members since 1998.

In France, President Francois Hollande is the most unpopular president in his country’s modern history and would be routed if he stands in next year’s presidential elections, according to opinion polls.

Centre-left parties recently lost power in Denmark, a stronghold of social democracy, and registered their worst-ever results in Finland and Poland. In Greece, support for the once dominant Pasok has plunged to just six percent.

“Social democracy is a shadow of itself,” German political analyst Albrecht von Lucke said on NDR television channel. “We are dealing with decline of historic proportions.”

The bad news?  While the center right and populist parties are benefitting, many near-left voters are moving even further left.
