On the surface, the election of 1872 might seem insignificant in US history; Ulysses Grant easily won reelection to the White House and his Republican Party maintained their dominance in both houses of Congress. In the south, however, the violence that followed the election at the state and local level was an ominous sign that the era of Reconstruction might soon be over. And, according to Dana Bash and her co-author David Fischer, nowhere saw more violence than Louisiana.

In this episode, Dana joins Ben & Bob to discuss her new book America's Deadliest Election: The Cautionary Tale of the Most Violent Election in American History, and how the violence that followed the 1872 election in Louisiana – including the slaughter of 150 unarmed black Americans in the small town of Colfax – laid the foundation for the restoration of white supremacy in the south.

Dana Bash is chief political correspondent at CNN, where she also anchors Inside Politics and co-anchors State of the Union alongside Jake Tapper.
