I'm assuming the SVP carried every municipality. They did win the five with Italian speaking majorities:
Bolzano/Bozen: Italian 73.80%; SVP 22.2%, PD 22.2%, Greens 11.4%, Forza/Lega Nord 8.2%, L'Alto Adige nel cuore 7.8%, Five Star 7.3%, Unitalia 7.3%, Freiheitlichen 4.4%
Laives/Leifers: Italian 71.50%; SVP 27.5%, PD 22.3%, Forza/Lega Nord 9.1%, Five Star 7.8%, Greens 7.3%, L'Alto Adige nel cuore 6.2, Freiheitlichen 5.5%, Unitalia 5.3%
Salorno/Salurn: Italian 61.85%; SVP 39.0%, PD 17.5%, Freiheitlichen 8.2%, Five Star 7.1%, Greens 6.9%, Forza/Lega Nord 6.6%, L'Alto Adige nel cuore 4.3%
Bronzolo/Branzoll: Italian 62.01%; SVP 36.0%, PD 17.5%, Greens 13.7%, Five Star 6.2%, Forza/Lega Nord 6.0%, Freiheitlichen 5.6%, L'Alto Adige nel cuore 5.5%, Unitalia 4.0%
Vadena/Pfatten: Italian 61.50%; SVP 41.5%, PD 15.0%, Greens 9.9%, Forza/Lega Nord 6.4%, L'Alto Adige nel cuore 6.2%, Five Star 6.0%, Freiheitlichen 5.7%
Was Italian-speaking turnout lower, or do some Italian speakers vote SVP?
------------------------------------------------------------------------------------
In the Ladin municipalities, the result was
SVP 59.8%
Freiheitlichen 15.5%
BürgerUnion/Ladins Dolomites/Wir Südtiroler 10.1%
Greens 5.9%
(others below 4%)
This is quite a big increase for Die Freiheitlichen (7.3% last time) and a big decrease for Ladins Dolomites compared with the 18.9% they got running on their own in 2008.
------------------------------------------------------------------------------------
And here's the supposedly 100% German speaking municipality of Martell:
SVP 340 (61.2%), Freiheitlichen 147 (26.4%), Südtiroler Freiheit 44 (7.9%), Greens 15, BürgerUnion/Ladins Dolomites/Wir Südtiroler 5, PD 2, Forza/Lega Nord 1, Unitalia 1, La Destra 1, everyone else zero.
