adjust the house of representatives to 1911 proportionality

[IowaStatePhiPsi]

The most recent expansion to the House of Representatives was in 1911, when the U.S. population was about 93 million, so a representative had 212,000 constituents. With the current population of 293 million, a representative has 674,000 constituents. To bring this number back to its 1911 value, the House should be expanded to 1370 members.
