> There is a level of detail that isn't practical to include in law. Isn't this the argument against unelected rulemaking? Suppose administrative agencies worked like this: They draft rules and then periodically submit them to Congress who decides whether to enact them. For uncontroversial changes this is essentially a rubber stamp, Congress defers to the experts' recommendations and passes the proposed rules. But no…
Congresspeople (or local legislators) do not have the expertise to evaluate the rules. Or even bandwidth. For example, the NEC is around 800 pages and is extremely technical. That's why these minutiae are delegated to agencies. But Congress can step in at _any_ point and override the decisions of individual agencies. The rulemaking process is also _extremely_ slow on purpose, giving Congress plenty of time to act.

[2] Laws have to go through a committee process before going to the floor; with more bodies, the committees could handle more work. Expanding the House would also make each seat less of a prize, reducing (but not eliminating) the impulse to gerrymander. Such an expansion would probably need to be accompanied by a serious conversation with the Capitol architect.
