The law-making process described, where a bill must go through multiple steps and can be rejected at various points, supports the principle of checks and balances in the U.S. Constitution.
Checks and balances are designed to prevent any one branch of government from becoming too powerful and to ensure that all branches have a role in the legislative process. In the case of a bill becoming a law, both the legislative branch (Congress) and the executive branch (the President) play critical roles. The bill must be passed by both the House of Representatives and the Senate before it can be sent to the President for approval. Additionally, even after passing both houses, the President has the power to veto the bill, adding another layer of scrutiny.
This process creates a system of accountability and oversight, reflecting the framers' intention to limit governmental power and protect democratic governance.
