That is to say, none of this has really affected the demographic composition of the Right's support, which looks as non-traditional and #trendz-based as ever. The CDX once again absolutely tanked in wealthy urban areas.
To add to Al's point, the one thing that really stands out for Italy to be a "muh trendz" country is the South. If you looked at Al's maps North of Molise, then yeah, you could easily make the case that Italy is basically aligning on the same basic electoral geography as the rest of Europe, with only a few ancestral remnants of the old order here and there. The South completely throws that narrative out the window, though. The right's results are well below average almost everywhere there, even in areas that were historically very right-wing! In relative terms, the right was significantly stronger there back in 2013.
You could wave it off by saying M5S are populists too, sure, but the fact that there are two brands of populism, increasingly at odds with each other (for all that Conte attacks Letta and PD, it's clear that he has no love lost for Salvini or anyone else on the right). This isn't a complication that you find in most European countries, and it will have significant consequences for how political conflict structures itself going forward. Furthermore, M5S' populism is a distinctly left populism - this time more so than ever, as they ran an almost single-issue campaign on preserving the minimum income they established. Given that, the fact that they do so well outside of large urban areas is notable. Even Mélenchon's vote became an overwhelmingly urban one in this past election. So whatever's happening in Italy, muh trendz only goes so far in explaining it.
Its also worth nothing that the entire south of the country is (mostly) devoid of immigrants. While the arrive in the south, they all move north for work, etc. A huge calling card of the right is cut off at its knees in part due to the South's long history of economic malaise.
