Key ideas in How the US Constitution Works
- The Constitution divides powers across three branches so no single group holds complete power
- Congress makes the laws, the executive branch carries them out, and the federal courts interpret them
- Separation of powers ensures the people who enforce laws do not also get to define or judge them
- Checks and balances give each branch specific powers to resist encroachments by the other branches
- The President can veto a bill passed by Congress to keep it from taking effect
- Congress can only override a veto if a two-thirds majority in both chambers votes to do so
- The framers designed the lawmaking process to be intentionally slow and demanding
- Gridlock prevents narrow, temporary majorities from pushing through hasty laws without broad consensus
- A slow legislative pace is a planned constitutional safeguard against sudden overreach, not proof of a broken design
- The constitutional system does not rely on leaders acting out of pure, selfless virtue
- Each official's personal ambition and desire to protect their own office's power drives them to check rivals
- By setting rival offices against one another, self-interest serves as a watchdog to protect constitutional limits
- Executive orders can direct agencies on how to carry out laws, but cannot invent new statutory powers or taxes
- All federal legislative power belongs to Congress, meaning the President cannot make up new laws unilaterally
- Courts can strike down executive actions that exceed the authority granted by the Constitution or federal statutes
- Under federalism, sovereign governing power is divided between state governments and the national government
