Chris Murphy, the junior senator from Connecticut, has made no secret of the fact that he’s mulling a presidential bid in 2028—and in traditional fashion, he’s got a new book out as a possible prelude. But whereas most tomes in this genre tend toward the soporific and self-serving, Murphy’s Crisis of the Common Good defies the rules of senatorial publishing in that it’s actually pretty damn good. It’s not a policy tract or meandering memoir, but instead tries to grapple with the larger issues that make this moment in our national life so fraught: how capitalism has gone awry, how technology is messing with our culture, how so many people feel lost and unmoored.
