By NICOLE WINFIELDROME (AP) â¿¿ Pier Luigi Bersani, the head of Italy's main center-left Democratic Party, won a runoff primary Sunday to become the main center-left candidate for Italy's 2013 general elections â¿¿ a vote that polls indicate could well be won by the Democratic Party given the utter disarray of the opposing center-right. Preliminary results gave Bersani 60.8 percent of the vote compared to Florence Mayor Matteo Renzi's 39.1 percent, with two-thirds of the votes counted. Even before the results were released, Renzi conceded the victory to Bersani in a Twitter message, writing: "It was the right thing to try, it was beautiful to do it together. Thank you all from the heart." The primary had been closely watched since the Democratic Party has a significant lead in the polls over former Premier Silvio Berlusconi's center-right People of Freedom party, which has been in chaos following the media mogul's 2011 downfall, a series of corruption scandals within party ranks and Berlusconi's indecision over whether to run for a fourth term. The 2013 general election â¿¿ expected in March or April â¿¿ will decide if Italy continues on the same path to financial health charted by Premier Mario Monti, appointed last year to save Italy from a Greek-style debt crisis. The former European commissioner was named to head a technical government after international markets lost confidence in then-premier Berlusconi's ability to reign in Italy's public debt and push through structural reforms. Monti has ruled out running for office but has said he would be willing to stay on in some capacity if he could be of service. Some commentators have floated the idea of Monti taking over the largely ceremonial role as Italian president, while others say his talents would be put to better use as treasury minister. Nearly all polls had projected Bersani would beat Renzi, who campaigned on an Obama-style "Let's change Italy now" mantra that attracted many disgruntled Italians back to politics. Renzi used his youth â¿¿ he's 37 â¿¿ to bolster his call for Italy's entire political class to be "scrapped."
