Gore rules out running for president in 2008

Al Gore, former vice-president and failed 2000 presidential candidate, announced that he will nor run for president in 2008 -- though he did not entirely rule out doing so further in the future.

He said: "I don't have plans to be a candidate again and though I haven't... completely ruled out any possibility of running at some point in the future I don't expect to and cannot perceive circumstances in which I would."
