It's silly season in the USA.
Here's the thing...being a "former Satanist" or having "dabbled in witchcraft" was practically a cottage industry among professional Christians during the late 80's and early 90's. Satanism was what suburbanites were panicked about before black people started moving in. So having come out of that was the ultimate conversion street cred.
Sort of like Vanilla Ice claiming to be from the streets of Miami instead of the cul-de-sacs of Dallas.
All of which is to say that I'd bet a substantial sum that Ms. O'Donnell's claims of witchcraft are an exageration at a minimum, if not outright bullshit. And since she is running as the uber-conservative candidate, I for one look forward to her deciding whether she'd rather be a witch or a liar.
