"By the time the next decade rolled around, members found themselves reluctant to dilute their votes, and the issue was never seriously considered again.
The result is that Americans today are numerically the worst-represented group of citizens in the country’s history. The average House member speaks for about 700,000 Americans. In contrast, in 1913 he represented roughly 200,000, a ratio that today would mean a House with 1,500 members — or 5,000 if we match the ratio the founders awarded themselves.
This disparity increases the influence of lobbyists and special interests: the more constituents one has, the easier it is for money to outshine individual voices. And it means that representatives have a harder time connecting with the people back in their districts."
