AP Government Unit 2 Essentials

The House and Senate weren't just created for efficiency — they were designed to represent fundamentally different interests. The House is fast (2-year terms, 435 members) and responsive to popular will. The Senate is slow (6-year terms, unlimited debate) and protective of state interests and deliberation. The filibuster and the 60-vote cloture threshold mean effective Senate action requires near-supermajority support, dramatically reducing the legislative majority's power. This structural friction is intentional — it forces compromise or kills bad legislation.

The Constitution gives the president surprisingly few explicit powers — command the military, negotiate treaties, make appointments, veto bills. But the presidency has grown into the dominant branch through executive orders, executive agreements, signing statements, and the bully pulpit. Hamilton argued in Federalist No. 70 that a single strong executive is essential for decisive governance. The 22nd Amendment's term limits and Congress's veto override and confirmation powers are the constitutional responses to this expansion. The ongoing debate is how expansive "executive power" really is under Article II.

Hamilton's Federalist No. 78 called the judiciary the "least dangerous branch" because it has neither sword nor purse — only judgment. But judicial review — established in Marbury v. Madison — gives the Court the power to strike down acts of Congress, executive actions, and state laws. Life tenure insulates justices from political pressure. The ongoing debate between judicial activism (use the courts to drive change) and judicial restraint (defer to elected branches) reflects fundamental disagreement about what democratic legitimacy requires. Courts can't enforce their own rulings — they depend on the other branches to comply.

The federal bureaucracy isn't in the Constitution — it grew from Article II's executive power. But with discretionary and rulemaking authority, agencies like the EPA and SEC create regulations that affect millions of people without direct congressional votes on each rule. The iron triangle shows how agencies, congressional committees, and interest groups can lock in policy outcomes that are hard for outsiders (including the president and Congress) to change. The merit system insulates career bureaucrats from political control — protecting expertise but also creating friction with elected officials trying to change policy direction.

Because power is divided across Congress, the presidency, the courts, and the bureaucracy, any one of those nodes can stop or slow a policy. Interest groups, citizens, and states can try to influence policy at any of these access points — if blocked in Congress, go to courts; if courts are hostile, try regulatory agencies; if the president is opposed, lobby Congress. This multiplicity prevents any one group from controlling policy, but it also means major policy change requires winning in multiple arenas simultaneously — explaining why American government is often gridlocked on big issues despite democratic majorities favoring change.
