No. Italy is much larger; from the EU’s perspective, unlike Greece, it’s too big to fail. It’s still growing; its economic problems are chronic, not acute. Slow growth there is attributable to domestic causes, not the euro and the EU in general. And it didn’t fudge its statistics.
Is Italy the new Poland or Hungary? No. I don’t see enough evidence of support for “illiberal democracy.” The citizenry is just upset about slow growth and immigrants, which should sound familiar to Americans.
The outcome of the election puts Italy in a position similar to where it was, say, 40 years ago; the largest party is considered unfit for government. The difference is that the EU only existed in embryo back then, which means that the rest of Europe has more of a stake in the Italian government than it did then.
It’s going to be a bumpy ride.
