Wow, what a weekend. Today we're looking on how down-ballot Republican candidates might be affected by Trump's debate performance and the now-infamous tape of him making extremely vulgar comments about women in 2005. Plus: Believe it or not there was some economic talk in last night's debate. Weirdly, a lot of it was about "carried interest." We'll talk about what that is and why you should care. Finally, a look at this year's Nobel prize for economics, which actually went to some research the layperson can understand.
