Journalist Tim Alberta grew up in a conservative, republican, evangelical church, where his father was the pastor. He wanted to know why so many evangelical Christians had become extremists, and ardent supporters of Trump. Over the past 4 years, he traveled to churches around the country, reporting on pastors and congregants who backed Trump, and those who felt forced out of their church because they couldn't support him. His new book is The Kingdom, the Power, and the Glory.
