Chapter 7 — Key Takeaways

On constitutional design

Article I comes first by design. The Founders made Congress the primary lawmaking branch. The institutional friction within it (House vs. Senate, supermajority requirements, internal procedural rules) is a deliberate feature, not an accidental flaw.
Congress has only the legislative powers "herein granted." The enumerated powers in Article I, Section 8 anchor congressional authority. The Necessary and Proper Clause, as read in McCulloch v. Maryland (1819), authorizes means rationally related to those ends.
The Commerce Clause and the power of the purse are the foundations of the modern federal government. Most of what the federal government does today rests on broad readings of those powers, both of which the Constitution explicitly assigns to Congress.

House and Senate are different by design. Two-year vs. six-year terms; population-based vs. equal-state apportionment; House minimum age 25 vs. Senate minimum age 30. The House was meant to be popular and responsive; the Senate deliberative and stable.
Equal Senate apportionment is constitutionally entrenched. Article V's only explicit unamendable provision protects equal Senate suffrage. The trade-offs are real and contested: defenders cite federalism, geographic diversity, and deliberation; critics cite departure from majoritarian democracy, partisan asymmetry, and compounding effects with the filibuster.
The House is capped at 435 by statute. Wesberry v. Sanders (1964) requires equal-population House districts within a state. The 2020 Census shifted seats from the Northeast and Midwest toward the Sun Belt; the 2030 Census is projected to continue the trend.

Members of Congress are wealthier, better-educated, more lawyer-heavy, older, whiter, and more male than the country at large. All gaps have closed somewhat; all remain.
Pitkin's typology distinguishes formalistic, descriptive, substantive, and symbolic representation. A member can be descriptively representative but substantively unrepresentative, or the reverse. Both matter; neither is the whole story.
Burke vs. delegate is a continuum, not a binary. Most members operate as politicos: trustees on low-salience technical issues, delegates on high-salience moral issues.

Voters dislike Congress and like their own member. The gap is persistent and large. Mechanisms include home-style cultivation, district tilt from gerrymandering and self-sorting, and asymmetric scrutiny of the institution vs. the individual member.
The paradox interacts with institutional dysfunction. If members are reelected for casework rather than legislative output, members face weak electoral incentives to legislate.

Dysfunctions are real, multi-causal, and not all of the same type. Bipartisan-structural: the fundraising treadmill, the budget mess, the decline of regular order. Polarization is bipartisan in occurrence even if its symmetry is contested. Gridlock is partisan-coded — each side blames the other.
Congress has handed major powers to the presidency. War-making, tariffs, regulation, emergency declarations — all delegated by statute, all difficult to reclaim. Both parties have contributed; neither has reclaimed.
Congressional capacity has eroded relative to executive capacity. Roughly 25,000–30,000 staff support a Congress meant to oversee an executive branch with millions of employees.

Bipartisan accomplishment is rare but possible. The 2021 IIJA, the 2022 CHIPS and Science Act, and other recent bills demonstrate Congress can still legislate at scale when conditions align. The cross-aisle relationship infrastructure is wearing down.
Institutional collapse is also possible. The 2023 Speaker's race shows what happens when small margins, organized factions, and weakened leadership conventions interact poorly.
Both halves of the picture are true at once. Cynicism (Congress is hopeless) and naïveté (Congress just needs better people) are both errors. The accurate view: this is what the institution was designed to do, this is what it actually does, and this is the gap.
