Repair California, a group that hopes to get two initiatives on the California ballot to obtain a new state constitution, will submit its proposed initiative language to the Attorney General on September 25. One initiative would authorize voters to call a constitutional convention; the other would actually ask the voters to take that step. Currently, only a two-thirds vote of the legislature can begin the process of considering a new constitution. The existing Constitution dates from 1879, although it was substantially revised in the period 1966-1974.
Also, another group, California Action Network, also plans to circulate an initiative to enable the voters to call for a Constitutional Convention. It has already received its language from the Attorney General, and its petitions are being printed now. See http://CaliforniaActionNetwork.com.
A recent neutral poll show that 70% of the voters would vote for calling a Constitutional Convention. If the initiatives get on the ballot, they would be on the November 2010 ballot. See this story. The proposals envision that the Delegates to the Constitutional Convention would be ordinary citizens, not state legislators.
