On The 21st: We speak with Washington Post reporter Dan Balz about political reporting in 2018. Also, we discuss a new initiative from the Illinois State Police which has created housing receptacles for discarding prescription drugs. And, we talk about severe food allergies and how they can affect your skin. But first, religion scholar Marie Griffith joins us to talk about her new book- Moral Combat: How Sex Divided American Christians and Fractured American Politics.
