This article evaluates the policy positions of President James Buchanan through the concept of latent opinion, or politicians worrying less about current public opinion and more about what it will be at the next election. Though Buchanan is often viewed as disconnected from the public’s opinions, the evidence shows that his positions on Kansas statehood and the acquisition of Cuba (or Mexican territory) were shaped by his perceptions of, and concerns over, what future public opinion would be in 1860. Though Buchanan was ultimately unsuccessful on both fronts, this study reveals that he was not simply unresponsive to public opinion, which is the common interpretation. Instead, the president’s policy positions were firmly tied to his views on latent opinion. Thus, the findings add a new dimension to scholarly understandings of James Buchanan’s policy priorities while displaying how latent opinion can be a beneficial construct in policy history.
