The official tally of votes has taken place over another glass of red wine and the completely objective report is as follows:
Santarpio's = 9 (60%)
Pizzaria Regina = 4 (27%)
Bianchi's = 2* (13%)
* one vote for Bianchi's was accompanied by a write-in of Umberto's. However, for this election, one vote was allowed, so the vote went to Bianchi's.
I am sad to note that no one offered to bribe the election official.
PS -- more qualitative evidence to come.
