The coalitions that sustained the traditional left parties in the West have collapsed

Yascha Mounk in Democracy:

Across the world, the right has, for the past decades, celebrated a remarkable string of successes. Far-right populists are now in power in countries from the United States to India, and from Turkey to Brazil. Even most of the democracies in which right-wing extremists remain comparatively weak are ruled by right-of-center, or at most centrist, leaders: Angela Merkel is now in the 14th year of her chancellorship in Germany, Scott Morrison was recently reelected in Australia, and Emmanuel Macron is the President of France.

In politics, one party’s gain is virtually always another party’s loss. While the right is dominant in most countries, the number of democracies ruled by the left now stands near historic lows. Spain, Portugal, Denmark, and Mexico have leftist leaders. Canada might be added to the mix, though the incumbent faces an uphill battle to stay in power at upcoming elections. That’s about it.

A lot of ink (some of it my own) has, in the past years, been spilled to explain the remarkable success of the right. This singular focus has made it more difficult to understand the equally significant transformations that have been taking place on the left side of the political spectrum: the ongoing decline and fall of social democracy; the rise and rapid fall of the far left; and the recent rise of green and liberal parties.
