Apple board member and former US vice president Al Gore would win the presidency if he ran for election, says Apple CEO Steve Jobs.

"If he ran, there's no question in my mind that he would be elected," Jobs told Time Magazine. "But I think there's a question in his mind, perhaps because the pain of the last election runs a lot deeper than he lets most of us see."

The report explains the background Gore's strenuous campaigning to persuade people to address the growing threat of climate-change caused environmental collapse.

"We have dug ourselves into a 20-foot hole, and we need somebody who knows how to build a ladder. Al's the guy," Jobs also told Newsweek. "Like many others, I have tried my best to convince him. So far, no luck."

Gore is known to be the Silicon Valley favourite for running for president on the Democratic ticket. Other Democratic hopefuls, Hilary Clinton and Barack Obama don't seem to have captured the level of support among America's tech-industry elite.

Gore almost succeeded in becoming president in the past. In a contentious election in 2000 he won the popular vote but lost the election, ushering in the era of George Bush.

The man puts his money where his mouth is: profits from his film, An Inconvenient Truth to the Alliance for Climate Protection.

Despite popular support, Gore maintains he has no plans to run for president.
