More Congressmen?

Democracy did a thing where they asked a bunch of people to write a short piece about a "big idea" of theirs. There's some good ones in there, but I thought the most intriguing one was Larry Sabato's out-of-left-field idea of expanding the House of Representatives to include maybe 1,000 members.

Sabato points out that smaller districts would be cheaper to run in, making it easier for grassroots challengers to have a shot at unseating incumbents. This seems plausible enough to me, though of course constitution reform is, in practice, impossible to do.
