Assume you were a person of the left and an atheist, and you decided to create a couple of people in a laboratory to discredit the Republican Party and white evangelical Christianity. You could hardly choose two more perfect men than Donald Trump and Roy Moore.

Both have been credibly accused of being sexual predators, sometimes admitting to bizarre behavior in their own words. Both have spun wild conspiracy theories, including the lie that Barack Obama was not born in America. Both have slandered the United States and lavished praise on Vladimir Putin, with Mr. Moore declaring that America today could be considered “the focus of evil in the modern world” and stating, in response to Mr. Putin’s anti-gay measures in Russia: “Well, maybe Putin is right. Maybe he’s more akin to me than I know.” Both have been involved with shady business dealings. Both have intentionally divided America along racial and religious lines. Both relish appealing to people’s worst instincts. Both create bitterness and acrimony in a nation desperately in need of grace and a healing touch.

I hoped the Trump era would be seen as an aberration and made less ugly by those who might have influence over the president. That hasn’t happened. Rather than Republicans and people of faith checking his most unappealing sides, the president is dragging down virtually everyone within his orbit.
