Little-known outside his home state until Donald Trump made him his running mate, Mike Pence—who proclaims himself a Christian first, a conservative second, and a Republican third—has long worn a carefully-constructed mask of Midwestern nice. Behind his self-proclaimed humility and self-abasing deference, however, hides a man whose own presidential ambitions have blazed since high school. Pence’s drive for power, perhaps inspired by his belief that God might have big plans for him, explains why he shocked his allies by lending Christian credibility to a scandal-plagued candidate like Trump.

In this landmark biography, Pulitzer Prize-winner Michael D’Antonio and Emmy-nominated journalist Peter Eisner follow the path Pence followed from Catholic Democrat to conservative evangelical Republican. They reveal how he used his time as rightwing radio star to build connections with powerful donors; how he was a lackluster lawmaker in Congress but a prodigious fundraiser from the GOP’s billionaire benefactors; and how, once he locked in his views on the issues—anti-gay, pro-gun, anti-abortion, pro big-business—he became laser-focused on his own pursuit of power.
