The centre-right continues to lose ground in the polls. According to YouTrend's Supermedia this week, the majority parties have fallen to 40.7%: for the first time in this parliamentary term, they are below 41%. If, on the other hand, one adds up the figures for the PD, M5S, AVS, IV and +Europa, the opposition parties reach 43.9%. This is the difference between victory and defeat under the new electoral law. The so-called Melonellum grants a massive bonus of 70 seats in the Chamber of Deputies and 35 in the Senate to the coalition that comes first, provided it clears the 42% threshold in both houses. If no coalition surpasses that threshold, seats are distributed on a purely proportional basis.

Among the parties, Futuro Nazionale (now at 7.7%), AVS (6.4%) and the PD (21.1%) are all up, albeit by just 0.1%. The positive sign is particularly significant for M5S, which is grappling with Nova, its grassroots consultation process. Giuseppe Conte's party gains a solid 0.4%.

The political forces supporting the government are either losing ground or holding steady: Fratelli d'Italia stands at 26.6% (down 0.3%), Forza Italia at 7.4% (down 0.2%), and Lega unchanged at 5.6% compared to last week. Among the smaller parties, the Supermedia records Azione at 3.3% (down 0.4%), Italia Viva at 2.3% (down 0.1%), +Europa at 1.5% (up 0.1%) and Noi Moderati at 1.1% (up 0.1%).
