Is he or isn't he, part 2 (Updated below)

David Roberts at Huffington Post has the video of Gore's opening statement to his testimony to the House. He also sets forth Gore's extensive legislative proposals and remarks, "My initial reaction is that Gore is going for the whole enchilada. He's pushing the envelope. These are radical proposals. To me, that indicates almost beyond reasonable doubt that Gore is not running for president."

That's not an unreasonable conclusion, particularly given the timidity of Democratic politics in recent years, but I wonder whether it's accurate. One possibility I've considered recently is that Gore may not be using the global warming issue to fuel his political amibitions as his detractors claim (as if that's somehow ignoble). Rather, I wonder if he's keeping speculation about a presidential run alive in order to maintain attention to the global warming issue.

Or maybe not. But I will say this. Gore's response to the recent brouhaha about his personal energy use was pretty tepid for a person with a presidential bid in mind.

So the mystery continues. The only thing that's clear is that he hasn't publicly, firmly ruled out a 2008 run.

UPDATE: I swear, I wrote this post before I read this.
