What is the theory behind the cube root thing? I am just curious. That is about 330 districts in California by the way. Do we really want that many nebbishes and losers prowling around Sacramento getting into trouble at taxpayer expense? It is bad enough just having 40 and 80 clowns (and most of them are clowns) up there for the respective chambers.
The theory is based on actual legislatures around the world. By coincidence, legislature size correlates strongly with the cube root of the population. (The US is, here, the exception rather than the rule.)
