Via David Frum’s How to Build an Autocracy published in the March 2017 issue of The Atlantic:
What excites Trump is his approval rating, his wealth, his power. The day could come when those ends would be better served by jettisoning the institutional Republican Party in favor of an ad hoc populist coalition, joining nationalism to generous social spending—a mix that’s worked well for authoritarians in places like Poland. Who doubts Trump would do it? Not Paul Ryan. Not Mitch McConnell, the Senate majority leader. For the first time since the administration of John Tyler in the 1840s, a majority in Congress must worry about their president defecting from them rather than the other way around.
