I'm not really sure what to think of that. I haven't really kept up with Italian politics since I left, and much has changed. Though as always, much hasn't.
Evidently much of what Renzi wanted was to centralize the government further, reducing the power of the provinces, and of the Senate. And he wanted to increase his own power; Italians tend to be leery of that.
They also feel strongly about their home province. Some people here feel that way about the state, and even town, where they were born, but we're a far more mobile society in general. Not many Italians move far from their original homes. They may get a job elsewhere, but that doesn't mean they'll live there. I knew someone who lived in Milan and taught in Bari; he'd fly down for three days a week. Another lived in Florence and taught in Trieste. He and his colleagues arranged to teach one week on, one week off. Neither would have DREAMT of moving to either place.
I suspect that attitude had something to do with Renzi's loss. I'll ask some friends there what they think.
But at least Renzi got his State Dinner.
