> If you expand the house by ~50x

Wow, that's a lot! I recall reading a piece, I believe in the Washington Post, sometime within the past few years, on this topic. They didn't run the numbers for such a dramatic increase, but I think talked about a House size of around 1000 representatives. And I was surprised to find out that this didn't shift the balance of power as much as I expected it would.

But regardless, as much as I would like for it to be easier for Democrats to win elections (in what would be an entirely fair way for them to do so!), that just puts one party in power more frequently. It doesn't fix the underlying dysfunction.
