The Italian experience provides a blueprint for how to defeat Mr. Trump. Only two men in Italy have won an electoral competition against Mr. Berlusconi: Romano Prodi and the current prime minister, Matteo Renzi (albeit only in a 2014 European election).

In different ways, both of them are seen as outsiders, not as members of what in Italy is defined as the political caste.
