Question

Quizplus · Accepted Answer

The Constitution establishes a system of checks and balances among the branches of government, including a system of shared powers between the executive (president), legislative (Congress), and judicial branches. This means the president often needs the support of Congress to enact significant policy changes, hence the effort to gain support for their initiatives.
