Personally, I will take Al Gore more seriously when I see him actually driving one of the thimbles he thinks the rest of us ought to be driving; when I see him giving up his private jets, and his “high consumption lifestyle”. At least, at that point, he will have the virtue of honesty. Maybe.
As it stands, he does not.
Addendum: (David L) Just as surley as the Sun rises in the East, the folks at Think Progress  are upset. what yet again, that one their heros has been smeared by the right wing:
The right-wing is angry that Al Gore has won so much public attention and goodwill for his work on global warming. Determined to smear his efforts, Drudge writes in a screaming headline:
While I find rating a person’s greenworthy rating in terms of the size of his house and his energy consumption to be so much Barbara Striesand, I’d find more amusing to give green rating is terms of waistlines. Al is a big boy, and big boys need to eat a lot of food and Gore certainly does.
