Uh, no. Stuart Buck writes:

One weird bit from a New Republic post on McCain’s choice of Sarah Palin (it seems to be credited to professor Alan Wolfe, but surely he wouldn’t say something that is without evidence): Sarah Palin named two of her children after witches, once took drugs, and refused to sign a bill forbidding domestic benefits for gay couples.It’s unclear where this “witches” claim is coming from, although I suspect it’s due to this post from Andrew Sullivan: A reader plumbs the weirdness: “Willow” was Buffy the Vampire Slayer’s best friend and “Piper” was the eldest sister on the series Charmed played by Shannen Doherty. The governor obviously has a penchant for television shows of paranormal female empowerment.Alas, one problem for this theory is the timing: Buffy the Vampire Slayer didn’t start airing until 1997, whereas Sarah Palin’s daughter Willow is described as being 14 years old. I don’t know whether she turned 14 this year or will turn 15 later this year, but I’m pretty sure that 2008 minus 14 equals something before 1997.
Otherwise, that’s a great theory . . .

Update: From a reader:

People Magazine interview Where do your children’s names come from? TODD: Sarah’s parents were coaches and the whole family was involved in track and I was an athlete in high school, so with our first-born, I was, like, ‘Track!’ Bristol is named after Bristol Bay. That’s where I grew up, that’s where we commercial fish. Willow is a community there in Alaska. And then Piper, you know, there’s just not too many Pipers out there and it’s a cool name. And Trig is a Norse name for “strength.” Sullivan should really consider being a KOS diarist.
