Mexican Presidential Election Results Delayed Until Wednesday

Mexico's presidential election was too close to call Sunday, with a leftist offering himself as a savior to the poor and a conservative free-trader both declaring themselves the winner. Officials said they won't know who won for days.

Electoral officials said they could not release the results of Sunday night's quick count of the votes, which they previously said would happen only if the leading candidates were within one percentage point of each other. Luis Carlos Ugalde, president of the Federal Electoral Institute, said an official count would begin Wednesday, and a winner will be declared once it's complete.

Felipe Calderon, 43, of outgoing President Vicente Fox's National Action Party, had 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.

Fox appealed for calm amid fears that a close result would raise the potential for violence.

Thousands of Lopez Obrador supporters, waiting for hours in the cold rain in Mexico City's central plaza, began shouting "Fraud! Fraud!" when Ugalde came on live television to announce the delay. Lopez Obrador said late Sunday that he would respect the delay in declaring a winner, "but I want the Mexican people to know that our figures show we won."

Calderon spoke minutes later, saying he too will respect the results — but that the official preliminary results, as well as the exit polls, show that he's the winner.

"We have no doubt that we have won," he said.

The race exposed deep divisions between Mexico's rich and poor in a nation desperately trying to match the success of its northern neighbor.
