(Newser) – Bill Clinton's former VP says he won't endorse Hillary Clinton—at least not yet. "It's still too early, in my opinion, to endorse a candidate or pick a candidate," Gore tells People in an interview to kick off his 24-hour climate-change telethon Friday. "Everybody can look at how the presidential campaign is developing and get some pretty clear ideas about how they think it's going to turn out, but I still think it's premature." Think he could still enter the ring himself? Not likely. "I'm a recovering politician, and the longer I go without a relapse, the less likely one becomes," he says.
