This theory argues that the president can act decisively in foreign policy more than in domestic policy, and that some presidents are more successful abroad.

• A. Unitary executive theory
• B. Two presidencies thesis
• C. Democratic deficit
• D. Realism

Answer: (B)

Two presidencies thesis explains that the president operates in two spheres: foreign policy and domestic policy. In foreign affairs, the presidency tends to be more decisive and able to move quickly, with international crises often yielding unity and national focus that support swift action. Domestic policy, however, is constrained by Congress, federalism, interest groups, and competing public opinions, making ambitious reforms harder to push through. Because of these structural differences, some presidents achieve notable successes abroad while facing tougher challenges at home. This idea captures why a president might seem more effective overseas than domestically.

Other concepts shift focus. Unitary executive theory emphasizes broad presidential control over the entire executive branch, not the specific foreign-versus-domestic dynamic. Democratic deficit deals with a gap between democratic ideals and actual political power, not the presidency’s relative effectiveness in different policy areas. Realism is a theory about state behavior in international relations, not about how individual presidents fare across policy domains.
