Concepts made simple

• Midterm electionsCongressional elections halfway through a president’s term. The whole House and a third of the Senate, but not the presidency.
• House versus SenateTwo chambers, two clocks. 435 members for two years against 100 senators for six, and a law needs both.
• Redistricting and gerrymanderingEvery ten years the lines are redrawn. Who draws them can decide a seat before a single vote is cast.
• Filibuster and clotureEnding debate in the Senate takes 60 votes. Passing the bill takes 51. The first number is the one that matters.
• How a bill becomes lawCommittee, floor, the other chamber, the president. Most bills never leave the first stop.
• Veto and overrideThe president can say no. Two thirds of each chamber can say yes anyway.
• Government shutdownNo appropriations law, no spending. What stops, what continues, and how it ends.
• Lame duck sessionTwo months when the old Congress keeps voting after the voters have replaced it.
• Budget reconciliationThe one road around the filibuster: a budget bill that passes the Senate with 51 votes.
• ImpeachmentThe House charges, the Senate tries. Impeachment is the accusation, not the removal.
• Senate confirmationThe president nominates, the Senate consents. Cabinet, ambassadors and every federal judge.
• Speaker of the HouseElected by the whole House, but leader of the majority party. Second in line to the presidency.
• PrimariesThe election before the election. Each party picks its nominee, and in a safe seat that is the whole contest.
• Certification and recountsElection night numbers are unofficial. The count, the check and the certificate come after.
• FederalismFifty states and one national government, each with its own laws, courts and elections.
• Judicial reviewCourts can strike down a law that conflicts with the Constitution. The Constitution does not say so; a court did, in 1803.
• Debt ceilingA legal cap on borrowing to pay for spending Congress already approved. Not the same as a shutdown.
• Committees: where laws are writtenThe floor votes, but the text is written in committee. That is also where Congress watches the executive.
• What to do between electionsVoting is only the start. Four plain ways to keep a hand on Congress for the next two years.
• Regulations: the rules under the lawsCongress sets the principle, an agency writes the details. Here is how a rule is made, and how it can be undone.
