The campaign memoir is an American tradition with a few signature ingredients. These include a flattering headshot, a title superficially stirring but actually meaningless (see Kamala Harris’s “The Truths We Hold” or Ron DeSantis’s “The Courage to Be Free”) and above all a text that is gently self-congratulatory and so insipid as to be entirely unmemorable. Kristi Noem, the telegenic Republican governor of South Dakota plainly angling to be Donald Trump’s running-mate, has released her own contribution to this grand literary tradition. It succeeds on only two of these three counts: the photo looks expensively posed (with a gilt clock and feminist placard in the foreground and an American flag in background), and the title (“No Going Back”) is suitably vapid. But the contents are unfortunately memorable in the worst possible ways.
