Overall opinion is about the same...he's finally speaking his mind, which is good, he was too robotic and programmed in his run for President. Although overall I liked him better then than I do now, so, it's a push.
The problem with Al Gore speaking his mind is that he appears to have lost his mind. If that's the case, he'd be far better off shutting up.
It proves in a way how inauthentic a person he always was. He has gone from a conservative southern Democrat to a hard-left populist. People don't normally have such a radical change in political views sincerely at his age.
