United States Congress Study Guide

📖 Core Concepts Bicameral Congress – Two chambers: the Senate (100 members, equal‑state representation) and the House of Representatives (435 voting members, population‑based districts). Constitutional Basis – Article I vests all legislative power in Congress; the Necessary and Proper Clause lets it enact laws needed to execute those powers. Enumerated Powers – Taxation, borrowing, commerce regulation, coinage, post offices, patents, courts, war‑making, etc. (Article I, §8). Exclusive Powers – House originates revenue bills; Senate ratifies treaties (2/3) and gives “advice and consent” on presidential nominations. Terms & Sessions – Senate: 6‑yr terms, ⅓ elected every 2 yr. House: 2‑yr terms, all seats each even year. Each Congress spans two years, usually split into two annual sessions. Apportionment – Decennial Census → 435 House seats fixed by the Reapportionment Act of 1929; each state gets at least one seat. Checks & Balances – Impeachment (House = simple majority, Senate = 2/3 to convict), power of the purse (appropriations), oversight via committees and subpoenas, and the Speech/Debate Clause protecting legislators. --- 📌 Must Remember Senate composition: 2 senators per state → 100 voting members. House composition: 435 voting members + 6 non‑voting delegates (DC + 5 territories). Age / Citizenship requirements: House ≥ 25 yr, 7 yr citizenship; Senate ≥ 30 yr, 9 yr citizenship. Revenue bills: Must originate in the House (Article I, §7). Treaty ratification: 2/3 Senate vote required. Veto override: 2/3 majority in both chambers. Pocket veto: President’s inaction + Congress adjourns → bill dies. Impeachment thresholds: House simple majority; Senate 2/3 to convict. Twenty‑seven Amendment: Pay raises take effect after the next House election. Necessary & Proper Clause: “All necessary and proper” to execute enumerated powers → basis for implied powers. --- 🔄 Key Processes Bill Introduction Only a member may introduce a bill (H.R. in House, S. in Senate). Committee Referral & Mark‑up Assigned to relevant committee → hearings → markup (debate, amend, vote). Committee Report Reported out → placed on calendar; can be “tabled” (killed). Floor Consideration Debate, further amendments, and vote in the originating chamber. Second Chamber Action Same steps in the other chamber; differences lead to conference committee. Conference Committee Resolves version differences; produces a conference report. Presidential Action (10‑day window, excluding Sundays) Sign → law. Veto → return to Congress. No action & Congress in session → law (default). No action & Congress adjourned → pocket veto. Veto Override 2/3 vote in each chamber → bill becomes law despite veto. Impeachment Flow House drafts and votes articles of impeachment (simple majority). Senate holds trial; 2/3 conviction required. --- 🔍 Key Comparisons Senate vs. House (Representation) – Equal‑state (2 per state) vs. Population‑based (435 seats). Revenue Bills Origin – House only vs. Senate cannot originate them. Treaty Power – Senate (2/3) vs. House (none). Voting Method – Senate roll‑call; House voice vote or electronic; VP only breaks Senate ties. Term Length – Senate 6 yr (staggered) vs. House 2 yr (all). Quorum – Majority of members in each chamber (simple majority). --- ⚠️ Common Misunderstandings “Congress can’t start a war.” – Congress may declare war, but presidents often initiate military actions; the War Powers Resolution tries to limit this. “The Vice President votes on every Senate matter.” – VP only votes to break ties. “All bills need a presidential signature.” – If the President takes no action for 10 days while Congress is in session, the bill becomes law automatically. “Judicial review is in the Constitution.” – It was established by Marbury v. Madison (1803), not explicitly in the text. “Non‑voting delegates have no influence.” – They can serve on committees and speak on the floor, just not cast final votes. --- 🧠 Mental Models / Intuition “Two‑Chamber Relay” – Think of a bill as a baton: House runs first (originates revenue), passes to Senate, which may tweak and send back. If the baton arrives with different versions, the conference committee is the “hand‑off point” to reconcile. “Checks = Levers” – Visualize each branch holding a lever: Congress’ lever is the purse (funds); the President’s lever is the veto; the judiciary’s lever is judicial review. The balance of power is the tension among these levers. “Population vs. Equality” – The Connecticut Compromise is the see‑saw: House tip (population) vs. Senate tip (state equality). --- 🚩 Exceptions & Edge Cases Pocket Veto – Only when Congress adjourns during the 10‑day presidential review period. Treaty Ratification – Requires exactly two‑thirds of present Senators, not just two‑thirds of those elected. Impeachment Conviction – The Constitution specifies no super‑majority for removal of the President; a 2/3 Senate vote is required, but a simple majority can remove other officials (e.g., judges) under certain statutes. Twenty‑seven Amendment – Does not block cost‑of‑living adjustments (CLOs). --- 📍 When to Use Which Identify the source of a legislative idea – If it’s a revenue measure, start in the House; if it’s a treaty or appointment, focus on the Senate’s advice‑and‑consent role. Deciding on a veto strategy – Use a pocket veto when Congress is scheduled to adjourn within the 10‑day window; otherwise, a regular veto allows for an override attempt. Choosing the appropriate oversight tool – For executive‑agency compliance, use committee subpoenas; for constitutional challenges, rely on judicial review. --- 👀 Patterns to Recognize “Even‑year election → all House seats up” → anticipate potential turnover and shifting majorities. “One‑third Senate election cycle” → predict which classes of senators face election and possible shifts in party balance. “Conference committee only when versions differ” → if both chambers pass the same bill, skip this step. “Non‑voting delegate presence on committees” → they may influence markup even though they can’t vote on final passage. --- 🗂️ Exam Traps Distractor: “The Vice President can vote on any Senate bill.” – Wrong: VP only votes to break a tie. Distractor: “A bill becomes law only after the President signs it.” – Wrong: It can become law without a signature if Congress is in session after the 10‑day period. Distractor: “Only the House can impeach and try an official.” – Wrong: House impeaches; Senate tries. Distractor: “The Senate can originate revenue bills.” – Wrong: Constitution requires House origin. Distractor: “Judicial review is granted by the Constitution.” – Wrong: Established by Marbury v. Madison. Distractor: “Non‑voting delegates have full voting rights on the House floor.” – Wrong: They may speak and serve on committees but cannot cast final votes. ---
