Swing Around the Circle refers to a disastrous speaking campaign undertaken by U.S. President Andrew Johnson between August 27 and September 15, 1866, in which he tried to gain support for his mild Reconstruction policies and for his preferred candidates (mostly Democrats) in the forthcoming midterm Congressional elections. The tour received its nickname due to the route that the campaign took: "Washington, D.C., to New York, west to Chicago, south to St. Louis, and east through the Ohio River valley back to the nation's capital".
Johnson undertook the speaking tour in the face of increasing opposition in the northern states and in Washington to his lenient form of reconstruction in the south, which had led the southern states largely to revert to the social system that had predominated before the Civil War. Although he believed he could regain the trust of moderate northern Republicans by exploiting tensions between them and their Radical counterparts on the tour, Johnson only alienated them more. This caused a supporter of Johnson to say of the tour that it would have been better "had it never been made."
Johnson had first intended his approach to reconstruction as a delivery of predecessor Abraham Lincoln's promise to benevolently "bind up the nation's wounds" after the war was won. However, as Congress began enacting legislation to guarantee the rights of former slaves, former slaveowner Johnson refocused on actions (including vetoes of civil rights legislation and mass pardoning of former Confederate officials) that resulted in severe oppression of freed slaves in the southern states, as well as the return of high-ranking Confederate officials and pre-war aristocrats to power in state and federal government. The policies had infuriated the Radical Republicans in Congress and gradually alienated the moderates, who along with Democrats had been Johnson's base of congressional support, to the point that by 1866 the Congress had gathered enough antipathy towards the President to enact the first override of a Presidential veto in over twenty years, salvaging a bill that extended the life of the Freedmen's Bureau. Johnson also managed to alienate his own cabinet, three members of which resigned in disgust in 1866.
