Another White House run? A former aide says Gore is considering it

Al Gore in 2008?

As the denials keep coming in the present tense -- "he's not running" isn't the same thing as "he won't run" -- an unidentified "former advisor" tells the Wall Street Journal that Gore is considering the possibility. "I do know that he's thinking about it. I know for a fact," the former advisor says. "He's talked to people about the pros and cons."

The Journal lays out one scenario for a Gore run: The former vice president's "fame and fund-raising potential" could allow him to "remain noncommittal and enter the presidential fray late" as an outsider alternative to Hillary Clinton.
