President Obama giving the State of the Union in the House chamber. It is very difficult to call the Los Angeles County Board of Supervisors a "representative body." After all, LA County is home to roughly 10.4 million residents, and has just five county supervisors to represent them. What this means, for those averse to division, is that each member of the board is tasked with representing a shade over two million people. A pending measure in the state legislature will increase the size of any county board serving a population north of two million residents from five to seven members.
