This doesn't jibe with the current House and Senate, where the equal-population represented House has a substantial Republican edge and the Senate has a majority of Democrats.
Edit: btilly below is right, the House isn't technically proportional representation, it's equal-population districts. Still, state by state representation doesn't seem to be breaking reliably for Republicans.
