I'm not sure that one could say that the governor was of any single party up to 1959 when they filed to run in both primaries:
In American politics, cross-filing (similar to the concept of electoral fusion) occurs when a candidate runs in the primary election of not only his own party, but also that of one or more other parties, generally in the hope of reducing or eliminating his competition at the general election.
Cross-filing in California elections, 1913-1959
In 1909, California introduced the direct primary election in its elections. The state's requirement that candidates in primary elections certify that they had supported a particular party in the previous general election was struck down by the California Supreme Court in 1909, in a case involving the Socialist Party of America. While the California State Legislature attempted to institute a looser test in 1911, by 1913, there was no longer any restriction on candidates filing in multiple primaries. The cross-filing provision was added to a previously debated primary bill by members of the administration of Governor Hiram Johnson, who had previously run (on separate occasions) as a Republican and with the Progressive Party.
Moreover, the looting of the taxpayer really didn't take off until Gov. Pat Brown (D) started the spending spree. Ronald Reagan as governor was forced to increase taxes to pay for Pat Brown's expansion of government spending and it was the further spending increases of Jerry Brown that caused the bled-out California taxpayer to create Proposition 13. The voters sort of held the line during the 80's and 90's with Republicans until Gray Davis who was so bad he was recalled and replaced with hornless RINO Schwarzenegger. Schwarzenegger did veto 1970 bills, so at least he tried to contain the airheads in the legislature. Since Schwarzenegger, Jerry Brown has returned to the governorship and the California taxpayer has assumed the position of leech-food.
California governors and their use of the veto since 1967
Gov. Jerry Brown vetoed about 12 percent of the bills passed by the state legislature in 2012, the second lowest veto percentage since 1996 when then-Governor Pete Wilson vetoed just under 9 percent of the bills that came across his desk, according to research by the Senate Committee on Governance & Finance.
On the whole over his 10-plus years in office -- from 1975 to 1982 and from 2011 to 2012 -- Brown has signed 12,744 bills, which is the most since 1967. He also has the fewest number of vetoes over that time period: 773.
Brown's use of the veto is much lower than that of his predecessor Gov. Arnold Schwarzenegger, who on average vetoed about 26 percent of the bills presented to him by state legislators between 2004 and 2010. It's also higher than Brown's previous stint as governor, when he vetoed about 4.6 percent of the bills passed by the legislature.
Here are some additional tidbits based on the committee's research:
- Brown's 2012 percentage is less than the average percentage since 1967 (13 percent).
- In 1982, Brown vetoed just 30 bills of the 1,674 he considered, setting the record for the lowest number of vetoes.
- The five years with the fewest chaptered bills have all been since 2007.
- Schwarzenegger vetoed over three times as many bills in his seven years (1,970) as Brown did in his first eight years (528), and twice as many as Reagan did in eight years (843).
