Vox suggests getting it straight from the vice-presidential candidates themselves. Joe Biden, before he was elected, and Paul Ryan, before he was nominated, penned their names to a book apiece. Read up on where these VP hopefuls stand.

Promises to Keep: On Life and Politics
By Joe Biden (2007)
Publisher: Random House, $10.20
Biden’s memoir is an intimate look at the chronology of the then-senator’s life from his Catholic upbringing in Delaware to his Senatorial debut at age 30 and his nearly 40 years of political experience. Biden expertly weaves in his personal narrative and political perspectives to create a rich opus worth reading even if he wasn’t the vice president. 
Young Guns: A New Generation of Conservative Leaders
By Paul Ryan, Eric Cantor and Kevin McCarthy (2010)
Publisher: Simon and Schuster, $6
Young Guns is a short, easy read that focuses on three up-and-coming Republican superstars, including vice presidential candidate, Paul Ryan. As the title suggests, this book is a somewhat quarrelsome read that pits Republicans and Democrats in several us-versus-them scenarios. If you’re looking to learn more about Ryan, this book is a good starting point, especially the section detailing his “road map for America’s future.”
