David Silverman, president of American Atheists, was recently seen on championing the importance of the atheist vote to American conservatives on the late night comedy show, Full Frontal with Samantha Bee. Silverman attempted to persuade Republican believers and non-believers alike that that there was a dire need to keep God out of politics by promoting his cause at one of the most important conservative gatherings in politics: CPAC.

The author of Fighting God: An Atheist Manifesto for a Religious World, Silverman is a loud-and proud-activist for atheism and is passionate about making sure the non-religious are included in the conservative conversation. In a spirited conversation with host Josh Zepps, Silverman argues that the rise of Donald Trump and Bernie Sanders heralds the end of religion’s grip on politics, and that if the Republican Party does not learn to appeal to atheist voters, they will inevitably be left behind.
