I'm not even sure this can be defined as, "a sign of the apocalypse." You see, as far as I'm concerned, when what is usually a proud and reliable mouthpiece of the Democratic party starts running positive pieces about Sarah Palin, well, bub, that pretty much defines the end of the world, far as I'm concerned.
From where I sit, Palin seems to make my center-left friends, especially the women, absolutely froth with rage. The folks who sit over on the left edge of the peanut gallery just explode impressively whenever her name comes up. It's really starting to eat into our cleaning budget, keeping up with that mess. I would have no problem voting for her, but I'm a card carrying member of The Vast Right-Wing Conspiracy. I'm capable of any evil as long as the end result is cutting taxes and shooting terrorists. Just ask the left side!
So, anyway, I think she has a very long way to go to sway centrist voters, but she does have quite a bit of time to travel. Like the article notes, politicians with bigger problems have overcome them to win the prize. That said, I'd feel more comfortable if the Republicans in that bunch had a more consistent track record.
