In the second installment of Politics with Amy Walter from Iowa, we contextualize the caucuses set to take place on Monday.

Democratic Strategist Matt Paul fills us in on why many voters are undecided until the last minute and what it will take to convince them to get behind a candidate. Chair of the Iowa Democratic Party Troy Price and Iowa Public Radio's politics reporter Clay Masters explain how the caucus process has changed since 2016. Iowa State University student Megan Johansen explains why she's supporting Pete Buttigieg. 

Also, Peter Ambler, the executive director of Giffords explains how the national conversation surrounding gun control has shifted, even in the suburbs.
