In The Last Caucus in Iowa, Jim O'Loughlin does for the Iowa Caucus what Anthony Bourdain did for restaurants. For over a year, O'Loughlin aimed to see as many presidential candidates as possible as they made their way through Iowa. His quest took him to meeting halls, living rooms, and more than a few craft brew pubs, and the result is a celebration of the state of Iowa and a cautionary tale about the Iowa Caucus. Chronicling a process that is alternatingly quirky, messy and inspiring, The Last Caucus in Iowa is a book for anyone interested in presidential politics and how it all begins.
