candidate for US senate admitted that she had dabbled in witchcraft as a high-schooler

This one is all over the news these days. Here is a British perspective, and a rather opinionated one --this is not a factual article but more of an editorial. What evidence in the text prompts me to say this? How much do you agree with the writer's perspective on all of the issues he discusses? Should candidates be judged on these sorts of things because it shows that they are hypocritical or that they lack judgment and common sense? Or is digging too far in the past and judging someone for it unfair? Finally, what's your opinion on witchcraft?
