“I don’t know what happened,” said French economist Jean Pisani-Ferry recently, lamenting President Emmanuel Macron’s unraveling grand centrist project.

His bewilderment is shared by disoriented centrists across the continent, all wondering how the ground has yielded under their feet as the tectonic plates of European politics continue to relentlessly shift, throwing the familiar into disarray.

But could this be the point of no return?

The first of the latest tremors was the political comeback of Czech populist billionaire Andrej Babiš, a self-proclaimed Trumpist and Euroskeptic agitator. His ANO party grabbed 35 percent of the vote in the country’s parliamentary elections last Sunday, leaving Petr Fiala’s pro-Western coalition behind at 23 percent.

Though falling short of an overall majority, Babiš — who lambasted the current center-right government for giving “Czech mothers nothing, and Ukrainians everything” — will no doubt relish teaming up with Hungary’s Viktor Orbán and the far-right parties of the Patriots for Europe group in the European Parliament to disrupt any centrist “more Europe” policies. And seeking to tug the country away from supporting Ukraine, he has already pledged to scrap Czech ammunition supplies to Kyiv.

Then, on Monday, French Prime Minister Sébastien Lecornu resigned just hours after appointing a cabinet, plunging the country deeper into a political quagmire with its fractious parliament and lame-duck president in a political system designed by Charles de Gaulle for a powerful head of state. Macron has appointed and lost five prime ministers in two years and is still floundering. Could we be seeing the death throes of the Fifth Republic?

At the end of the week, there will likely be more bad news for centrists in Portugal as well. Chega, the party of “God, fatherland and family” that in May became the official opposition, is set to do well in the country’s local elections — a harbinger of things to come.

These are indeed heady, giddy times for national-conservative populists — and they’re celebrating as their rivals remain confounded.

The outcome of the Czech election prompted the top populist leaders from across the continent to take to social media — including Orbán, Denmark’s Anders Vistisen, the Netherlands’ Geert Wilders, Austria’s Harald Vilimsky, France’s Marine Le Pen and Italy’s Matteo Salvini. “All across Europe, patriotic parties are being called to power by the people, who long to reclaim their freedom and prosperity!” Le Pen posted on X.

But how did we get here?

In the summer of 2024, European Commission President Ursula von der Leyen had crowed the “center is holding.” Following European Parliament elections that saw right-wing populists and national conservatives make serious inroads but fall short of the huge surge they were expecting, it seemed voters still largely backed centrists.

But von der Leyen was being complacent — a common characteristic of mainstream centrists from both the left and right since Brexit and U.S. President Donald Trump’s first election in 2016.

Centrists were too quick to dismiss both Brexit and Trump’s first term as aberrations. The world would right itself, they said. Even as late as 2023, the Global Progress Action Summit in Montreal — a gathering of center-left politicians — saw boisterous talk of another possible “progressive moment,” with the Third Way politics shaped by former British Prime Minister Tony Blair and former U.S. President Bill Clinton a quarter-century ago cited as an example.

But since those first populist shifts, the centrist crack-up has grown more apparent to everyone else. The British Labour Party’s general election win in 2024 was an outlier — testimony to the unpopularity of the Conservatives rather than an embrace of Prime Minister Keir Starmer or an indication of a political trend. And U.S. President Joe Biden’s 2020 win seemed more like a pause in the crumbling of the ancien régime.

Meanwhile, centrists on both the left and right have made too many excuses, without nearly enough rigorous self-analysis or readiness to challenge group-think or shibboleths. Instead, they’ve muttered about “deplorables” and blamed their setbacks on populists weaponizing issues like net zero, immigration, cultural disorientation, identity anxieties and the cost-of-living squeeze.

They’ve easily reached for Russian disinformation and demagogic manipulation to explain away their misfortunes — talking almost as though the here-and-now challenges and fears faced by ordinary families are made up or overblown. And they haven’t been able to ease the nagging widespread sense that the West is in a doom-loop of structural decline and lacks the political will to correct.

Centrists have consistently failed to understand that the jolts taking place under their feet were forewarnings of even bigger political earthquakes to come as the world changed. Now demoralized, either too laggardly to rethink policies or too quick to dress themselves in populist clothes — as Starmer’s Labour government is now trying to do with tougher immigration rules — more cracks are surely to come. Why vote for copycats when you can vote for the real thing?

In Germany, for example, Chancellor Friedrich Merz’s asylum crackdown has done nothing to stem the rising popularity of the hard-right Alternative for Germany party — at least in opinion polls. Merz’s approval ratings are dismal this month, with 70 percent of Germans unhappy with his performance.

So are national conservatives now unstoppable?

Maybe so, until the tectonic plates settle. Or at least until they’re exposed as having no real answers to the immense challenges of Europe’s anemic economic growth, poor competitiveness and massive public debt.
