Every president faces criticism and caricature. Donald Trump, however, is unique in that he is routinely characterized in ways more suitable for a toddler. What's more, it is not just Democrats, pundits, or protestors who compare the president to a child; Trump's staffers, subordinates, and allies on Capitol Hill also describe Trump like a small, badly behaved preschooler.

In April 2017, Daniel W. Drezner began curating every example he could find of a Trump ally describing the president like a toddler. So far, he's collected more than one thousand tweets-a rate of more than one a day. In The Toddler-in-Chief, Drezner draws on these examples to take listeners through the different dimensions of Trump's infantile behavior, from temper tantrums to poor impulse control to the possibility that the President has had too much screen time. How much damage can really be done by a giant man-baby? Quite a lot, Drezner argues, due to the winnowing away of presidential checks and balances over the past fifty years. In this book, Drezner follows his theme-the specific ways in which sharing some of the traits of a toddler makes a person ill-suited to the presidency-to show the lasting, deleterious impact the Trump administration will have on American foreign policy and democracy.
