“The Constitution’s framers worried that individual states might try to grab too much power in the House by creating dozens and dozens of congressional districts, so they specified that a district could not be smaller than 30,000 people. But they put no upper limit on district sizes. After the 1920 census revealed that urban Americans outnumbered rural Americans, the House in 1929 capped its numbers at 435 to keep power away from those urban dwellers, including immigrants, that lawmakers considered dangerous, thus skewing the Electoral College in favor of rural America. Today the average congressional district includes 761,169 individuals—more than the entire population of Wyoming, Vermont, or Alaska—which weakens the power of larger states”
