Democratic Sen. Kay Hagan agreed to three debates against Thom Tillis in July, and that did not include Tuesday night's debate. The solution? Tillis spent an hour talking to a statewide audience and an empty chair. Kasie Hunt weighs in. Plus, Adam Smith and NBC's Perry Bacon discuss the midterm battles in Florida and Georgia.
