Pitching his message to Oregon’s environmentally-conscious voters, Obama called on the United States to “lead by example” on global warming, and develop new technologies at home which could be exported to developing countries.

“We can’t drive our SUVs and eat as much as we want and keep our homes on 72 degrees at all times … and then just expect that other countries are going to say OK,” Obama said.

“That’s not leadership. That’s not going to happen,” he added.

Al Gore may think that, but Gore doesn’t actually have to lead, thank god.
