Four types of regions:

• regions the PD + IdV did relatively well in – that is, regions in which they increased their vote by more than they did nationally, in order: Lazio, Marche, Toscana, Umbria.
• regions the PD + IdV did relatively poorly in – that is, regions in which they increased their vote by less than they did nationally, in order: Sicilia, Campania, Basilicata, Abruzzi
• regions the PDL+LN did relatively well in, in order: Calabria, Sicilia, Campania;
• regions the PDL+LN did relatively poorly in, in order: Molise, Friuli-Venezia-Giulia, Umbria

So, the centre-left got stronger where it was strongly already, and had problems in the South; the PDL + LN did well in the South, in particular picking up voters in Campania, presumably due to the government’s highly visibly problems dealing with rubbish piling up on Neapolitan streets.

As a result of this, the PDL + LN won ‘extra’ seats (seats in addition to those they would have done had there been a uniform national swing) in Lombardia (+4), Campania (+1), and the Veneto (+1).
