why is it important for the president to share powers with congress
Powers of the President of the United States The Separation of Powers devised by the founding fathers was designed to do one primary thing: to prevent the majority from ruling with an iron fist. Based on their experience, the framers shied away from giving any branch of the new government too much power. The separation of powers provides a system of shared power known as "checks and balances". For example, the President appoints judges and departmental secretaries, but these appointments must be approved by the Senate. The president can veto bills, or deny them. If he does that, the bill is sent back to Congress.
Powers of the United States Congress Article I of the Constitution sets forth most of the powers of Congress, which include numerous explicit powers enumerated in Section 8. Constitutional amendments have granted Congress additional powers. Congress also has implied powers derived from the Necessary and Proper Clause of the Constitution.
