First wolves, now polar bears

From NBC's Carrie Dann

The Defenders of Wildlife Action Fund, which caused a stir by launching this ad slamming Palin on her support for aerial wolf hunting, is back.  Their newest offering, now running in Virginia and expected to expand to other battleground states, says that Palin has been"fighting efforts to protect the polar bear," allowing the species to be killed for trophies.

When the Interior Department was contemplating listing the polar bear as an endangered species, Governor Palin sued the federal government, saying that the bear population was "very, very healthy."  Last month, we noted that Palin's position is at odds with McCain's; the Arizona senator went out of his way to laud the government's concern over the plight of the polar bears, and he attributed the population's troubles, in part, to global warming.
