Mexico City ? Mexico at last will have a final decision Tuesday on its disputed July 2 presidential race, with the nation’s top electoral court expected to declare ruling party candidate Felipe Calderon president-elect.

But the long-awaited ruling by the Federal Electoral Tribunal – which comes two months, three days, and tens of thousands of pages of legal challenges after voters cast their ballots – is unlikely to end potentially explosive uncertainty or close the growing political divide gripping the country.

Most court rulings so far have favored Calderon, who has a 240,000-vote advantage over leftist rival Andres Manuel Lopez Obrador.

“We are very calm, very sure,” Juan Camilo Mourino, who heads Calderon’s transition team, said on Monday. “Tomorrow, Felipe Calderon will be president-elect.”

During an early morning session Tuesday, the seven magistrates of the Federal Electoral Tribunal will give their final count in the election and decide whether it was valid. While they have the power to annul the election, nothing indicates they plan to do so. The court’s decision cannot be appealed.
