Things are getting pushed more to the left, though a lot of people are stopping at liberalism I can definitely say that I've seen a lot more Italian leftists than say leftists in the U.S., recently the current party that had direct ties to fascism and an ex prime minister of Italy called Berlusconi (Italian Ronald Reagen, member of the Mafia, was a member of a openly fascist party) just lost a referendum that sought to weaken the justice system because they were getting caught and possibly charged for shit (some of it related to Epstein from what I know), which is the first time in a long time that the Italian right lost in votes, another thing that is pushing people left is the situation in Palestine, our current prime minister, Giorgia Meloni, is a trump and Israel bootlicker and she is wildly unpopular right now, so while things aren't perfect for the left here at least we're possibly getting rid of a fascist party being in power, though we'll have to wait for the upcoming elections for that.
It's also important to note Italy's political history, the constitution was by a large part written by communists and had one of the largest communist parties in the world during the cold war though it distanced itself from the soviet union taking a more moderate route, during this time the right wing parties that held power collaborated with the CIA to get rid of communism in Italy by doing a number of terrors attacks and blaming it on the left, which for a while worked, but recently the sentiment amongst a lot of Italians is moving to the left, albeit a more moderate, words like communism and socialism are getting more normalised which is a good thing.
Sorry for the late reply, got caught up in school work and i haven't been on here, but yes italy does have more than two parties, there's a number of parties that have large stances in government but unfortunately most of them are right wing, a lot infact having direct ties to mussolini's party, and most of the remaining "left-wing" parties are reformists and basically just liberals; i can't vote yet even tho I'm 18 because i don't have citizenship yet, (italy has a really thick beurocracy, despite living here all my life; the communist party I'm currently looking at is the ICP, italian communist party but I'm gonna be honest most communists here are leftcoms, ultras, eurocommunists, and overall a lot of liberals pretending to be communists; the elections themselves are a bit complicated to explain, i myself don't think I've gotten a good understanding but it's an indirect democracy, so there is a form of voting but who actually gets power is elected from within the government.
