Proposition 40 is a referendum on the State Senate Redistricting plan. It is an effort to redistrict the state of California and to change the current district boundaries. A “yes” vote means that the current districts, drawn by the California Citizens Redistricting Commission, remain the same. A “no” vote means that new boundaries will be drawn by a group appointed by the California Supreme Court.

Approving Proposition 40 would have no fiscal impact on the state or counties. Rejecting it would result in a one-time fee of approximately $1 million to the state of California and its counties. The money would go to establishing new Senate districts, precinct maps and related election material for the new districts.

The supporters of Proposition 40 include: Jennifer A. Waggoner-president of the League of Women Voters of California, David Pacheco-president of AARP California, Allan Zaremburg-president of California Chamber of Commerce, Charles Munger Jr.-activist in California ballot proposition policies, the California Democratic Party and most recently the California Republican Party.
