Giulio Andreotti, one of the longest serving and most controversial politicians in Italy, was rather frail in his youth, and suffered from chronic headaches as well; what if he'd died at some point in the 1940s, just like his father (Spanish flu) and sister (pneumonia) before him, how would Italian politics change? The Christian Democrats would still have a leading role in the first decades of the postwar period, IMO - they did have the CIA in their corner, after all - but would they be as dominant as they were IRL? If they happen on schedule, the Years of Lead might end up being slightly different as well, as Andreotti was tied to Gladio, not to mention the later mafia wars - since he knew infamous boss Totò Riina, too.
IMO, PCI and PSI would chip away at DC votes far earlier than they did IRL but, beyond that, I have no idea.
