Such dramatic findings have raised questions about the validity of the study; some even wonder whether it should've been conducted at all. But perhaps the most controversial aspect are the conclusions the authors drew: "We believe that the key difference between these two groups is that the married/engaged women have more invested in their relationship, and therefore have considerably more to lose if their current relationship were endangered," they wrote. As the lead author, Kristina Durante, was quoted as saying in the CNN article: married/ engaged women are "overcompensating" for those feelings, then going ever-more-certainly for the safe, conservative candidate that represents traditional values. In short: Not only is ovulation causing changes in voting, but it's because of women's husbands. Double whammy controversy. It's the same for single women voting liberal: They're more open during their ovulation cycle, the authors argue, and not concerned about spousal feelings.
