MEXICO CITY (AP) – Mexico’s presidential election was too close to call Sunday with voters bitterly divided between a leftist offering himself as a savior to the poor and a conservative warning his rival’s free-spending proposals threaten the economy.

Electoral officials were conducting a quick count of the votes, and were hoping to declare a winner later Sunday. But they warned that they would hold off – perhaps for days – if neither candidate had a large enough advantage.

Mexico’s two main television networks did not release the results of their exit polls, saying the difference was smaller than their margin of error.

Felipe Calderon, 43, of Fox’s National Action Party, has been running an exceedingly close race with Andres Manuel Lopez Obrador, 52, of the leftist Democratic Revolution Party. The Institutional Revolutionary Party’s Roberto Madrazo, 53, had been trailing in third place.
