I've been bingeing on antebellum history books lately, but I can't find any popular history books that cover the period after the Mexican War and before Lincoln's election. This would cover the presidencies of Taylor, Fillmore, Pierce, and Buchanan. Any suggestions?
So I ended up answering my own question. Just in case someone is curious in the future, The Impending Crisis by David M. Potter is a historical survey that covers 1848-1861.
