Obama/Gore '08?

Is this a possible endorsement teaser, or is something else in the works behind the scenes:

Barack Obama, last night in Portsmouth, N.H., advised a guy wearing a Santa hat to go to his Web site to learn more about his plan to combat global warming. And then he said this:

"I talk to Al Gore about every three weeks, and we're going to make sure that your home at the North Pole is still available to you," Obama said, reports NBC/NJ's Erin McPike.

When Obama was asked, at the same event, what one measure he would most like to see enacted in his presidency, he replied:

"I would enact a bold energy policy because I think that we could save so much money, engineer such a resurgence in our economy and solve climate change all at one time. And it would improve our national security posture. So you get a three-fer. It helps our environment, our economy and our national security and it would free up resources over time to deal with what I think is the most important domestic issue which is health care, and I think it would help us strategically on the international stage."

While this doesn't necessarily mean that Gore has been offered the second spot on an Obama ticket, it certainly does sound as if he has Obama's ear. It's been reported that while Gore has spoken with several of this season's presidential candidates, only Edwards and Obama have visited him at his home; Obama has on numerous occasions.
