A Turkish man casts his vote during the municipal elections at a polling station in Istanbul, on March 29, 2009. Some 48 million people are voting Sunday to elect mayors and district administrators in 81 provinces that Prime Minister Tayyip Erdogan hopes will strengthen his party's hand in pushing for constitutional reforms. Recent polls predict Prime Minister Recep Tayyip Erdogan's Justice and Development Party (AKP) will win Sunday's race, garnering at least 40 percent of the vote, with a large lead over its main rivals, the Republican People's Party (CHP) and the Nationalist Action Party.
