Whether discussing contemporary American political issues, Federalist opposition to Jeffersonian ideology, or the shape and texture of Texas politics, Jim Broussard evinced a keen understanding of what moved voters to act as they did.  His love of the political whirligig, combined with his analytical acuity, is evidenced on almost every page of Anatomy of an Upset. It makes a meaningful contribution to a better appreciation of the hinge election of 1961 as part of a broader, consequential shift in Texas partisan alignment.
