Italy’s right-wing parties, in banding together, have given themselves an overwhelming electoral advantage over the fragmented left, which failed, amid infighting, to create a comparable coalition. When polls were halted two weeks before the vote, a YouTrend projection showed the right-wing bloc commanding 45.9 percent of the support, compared with 28.5 for the center-left and 13.2 for the amorphous, vaguely anti-establishment Five Star Movement. Some pollsters say the Five Stars have made progress since that point by arguing for the preservation of their signature welfare plan — a so-called citizens’ income that is popular in the south. Meloni opposes it.
