The Both Sides Now weekend radio show -- along with the daily Both Sides Minutes -- exchanges ideas, not insults. It covers both sides so listeners decide for themselves. You'll hear from Arianna Huffington, president of the Huffington Post, and Mary Matalin, CNN contributor and former top aide in the Bush-Cheney White House. Sitting in for Arianna periodically will be Ron Reagan & Eliot Spitzer. Hosted by Mark Green.
