The governing centre-left coalition, whose parties are running separately because of their many disagreements, will end up in about the same place. Its biggest member, the Democratic Party, will get around 23 percent, but with various smaller allies it might make it up to 30 percent. Again, not enough.
Whereas Berlusconi's Forza Italia ('Let's Go, Italy'), running in tandem with the hard-right, anti-immigrant Northern League, could get as much as 40 percent of the vote. If they then make deals with a few small parties that verge on fascism, they could form a majority government. Berlusconi's great wealth, derived from his huge media holdings, would give him a dominant role behind the scenes in such a coalition, but he is legally barred from even running for parliament, let alone becoming prime minister. So who would it be?
The dark-horse candidate is Giorgia Meloni, the Trump-lite leader of one of the smaller parties, Brothers of Italy, but it would probably the Northern League's leader, Matteo Salvini. You might call Salvini Trump-heavy: he hailed The Donald's election as "the revenge of the people, of courage, of pride...and one in the eye for the bankers, the speculators and the journalists."
Italians are quite justifiably fed up with the way their country has been run in recent years. Unemployment is 11 percent, but among the under-25s it is close to 40 percent, and over 100,000 young people left the country last year in search of work elsewhere. Average family incomes, which fell dramatically after the 2008 financial crisis, have still not recovered to the 2007 level.
But the biggest issue is immigration: in the past four years Italy has received 600,000 illegal migrants, mostly from African countries, and all the major parties are promising to do something about it. Berlusconi talks bluntly about mass deportations, and his prospective coalition partners in the Northern League actually put a number on it: 100,000 forced 'repatriations' a year, presumably until they are all gone.
The outgoing coalition government has actually managed to cut the numbers arriving by making a deal with Libya, the point of departure for most of the migrant boats crossing the Mediterranean to Italy. In return for subsidies for the Libyan Coast Guard and various other considerations, the Libyans have been persuaded to try to stop the migrants from setting sail in the first place.
As a result, migrant arrivals dropped by a third in 2017. That ought to have won the centre-left coalition some credit with the electorate, but since the number of migrants who made it ashore last year was still 119,000, gratitude for the government's efforts was notably sparse. The centre-left coalition is the only major political grouping in Italy that has not fallen into the hands of populists – but that is why it is trailing both the others in the polls.
The Berlusconi-Salvini coalition's highly implausible commitment to send all the migrants home resonates strongly with an electorate that has had enough of politics-as-usual. The Italian constitution makes it very hard to form a majority government without an even broader coalition, so the result next Sunday may well be a hung parliament and another election soon, but anger and despair could still give the two men victory.
Since Donald Trump's election in November 2016, three Western European countries – the Netherlands, France and Germany – have had elections in which nationalist, anti-immigrant parties that are hostile to the European Union, or at least to the euro common currency, have done better than ever before, but have not won power. In Italy, they may actually win.
