I think this sort of true and also sort of not true. When looking at PD exclusively, their coalition, as Al said, looks a little less weird than last time, but this is largely because they lost some of their wealthiest supporters to the Third Pole, and re-gained some more working-class ones in certain regions (notably Liguria) from M5S. 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.
Its non-traditional for most Western European countries, but for Italy its not radically different to what has long been the case. I mean, its not like the PD have ever profiled themselves on their commitment to the proletarian cause...
