In a letter to be emailed to Barack Obama’s supporters, Al Gore wrote, “From now through Election Day, I intend to do whatever I can to make sure he is elected president of the United States.” The former vice president plans to appear with Obama at a rally in Detroit tonight.

ADDENDUM: OK, so this may not be big “news,” but do you think Gore’s late arrival and “do whatever I can to make sure he is elected” support will be an asset or a liability for Obama? Will Gore jet around the country making speeches on Obama’s behalf? Hmm … better not; the carbon offsets might bankrupt the Obama campaign. Maybe he should borrow Jane Fonda’s anti-war bus that ran on vegetable oil.
