I like Al Gore and I'd be quite happy for him to run for president, but I think speculating about the possibility is somewhat counterproductive. The fact is that there are plenty of good candidates running and no need for someone on a white horse to come in and save the day.
...adding, that probably wasn't clear. I mean that the perpetual speculation makes it sound as if things suck unless he runs, that we need a savior candidate. I have nothing against him choosing to run now or 6 months from now or whenever.
