make reapportion something that happens every 10 years with the census
That’s… the current state of affairs? New apportionments of Rep seats to states take effect on the 4th year of each decade and have done so consistently since 1933 and in particular the 1929 Permanent Apportionment Act. It also does little for the major structural issues with voting, which are much more about voting method and the drawing of voting district lines.
