Firstly I'll echo everyone else and say this is great work. As well though can I ask a question? My grandfather is from a small town in Avellino called Montefalcione and I was wondering how it votes, is this sort of information available?. Thanks in advance.
The Interior Ministry has a fantastic website which provides the results for every election of any kind since 1946. By using the menu on the right, you will find the results broken down by Region, Province and Municipality : http://elezionistorico.interno.it/index.php
For example, these were the results in your grandfather's town for the 2008 House elections. 
Looks like it's quite left-wing. FFs. 
Thanks a lot, that website is great. I'm just as pleased to see my relatives are very sensible
