Presidential success in Congress is determined by several factors, including the partisan and ideological makeup of Congress, the president's party control of Congress, and the ability of the president to build support and consensus within Congress. A divided government and party polarization often make Congress more willing to disagree with the president, resulting in less success for recent presidents. Presidents have a higher success rate earlier in their term and on bills for which they express a preference in advance. Overall, presidents are more successful on foreign policy than on domestic policy.
