A man casts his vote during a primary runoff, in Piacenza, Italy, Sunday, Dec. 2, 2012. Italians are choosing a center-left candidate for premier for elections early next year, an important primary runoff given the main party is ahead in the polls against a center-right camp in utter chaos over whether Silvio Berlusconi will run again. Sunday&#x27;s runoff pits veteran center-left leader Pier Luigi Bersani, 61, against the 37-year-old mayor of Florence, Matteo Renzi, not shown, who has campaigned on an Obama-style &quot;Let&#x27;s change Italy now&quot; mantra.
