MANILA, Philippines -- Yes, former president Joseph Estrada has a ?50-50 chance? of running in the 2010 presidential elections, but only as a last resort, a spokesman for the opposition said Tuesday.

Lawyer Adel Tamano said that Estrada's claim of possibly running again as president was a message ?for the opposition to come together.?

?[Estrada's] claim is consistent with the clamor of the people,? he said.

Meanwhile, Senator Benigno ?Noynoy? Aquino III said he was unsure whether it was legally permissible for Estrada to run for re-election.

?The Constitution only allows for the President to be elected once,' he said.

However, Tamano said that legal issues were a novelty and if Estrada would run, there would be a great chance that he would win.

?A fractured opposition leads to a successful administration,? Aquino said.

Tamano also said that opposition members would have to unite, citing the 2004 elections when the opposition was divided, enabling the administration to succeed.
