SACRAMENTO -- The last time one party held a two-thirds majority in the California Senate, President Lyndon Johnson was sending troops to Vietnam, Los Angeles was recovering from the Watts riots and the state's governor was named Brown -- Pat Brown.
That was 1965. Nearly half a century later, Democrats hope they are on the verge of again winning a supermajority in the upper house when voters go to the polls to fill 100 seats in the Legislature.
With a gain of two seats, the Democrats would have it, putting them halfway to their goal of nearly absolute power over California's policies and finances. A two-thirds vote of each house is required to raise taxes and overturn gubernatorial vetoes.
Neither party is expected to reach that threshold this year in the Assembly, which last had a supermajority in the 1970s when Democrats held it. But "the odds are very much in favor of the Democrats being able to get a two-thirds majority" in the Senate, said former GOP strategist Allan Hoffenblum.
The opportunity stems from last year's independent redistricting process, which created more swing areas; from a precipitous decline in Republican voter registration; and from financial troubles that plague the state GOP, limiting Republicans' campaign options.
Democrats, who currently hold 25 of the Senate's 40 posts, are spending hundreds of thousands of dollars on mail and TV ads in three swing districts where they believe they can pick up seats, according to Senate leader Darrell Steinberg, a Democrat.
"There is no guarantee, but certainly we have a great shot," Steinberg said.
Republicans are fighting back by playing to fears of what Democrats with a supermajority might do. Californians "don't want one-party rule," said state Republican Party Chairman Tom Del Beccaro.
But the GOP will be hard-pressed to match the Democrats' campaign cash. The California Republican Party had $203,000 on Sept. 30 after spending $1 million during the previous three months. The Democratic State Central Committee spent $4 million during that time and had $13.8 million in the bank.
"There is no doubt the Democrats are going to outspend Republicans in . . . all the races," said Dave Gilliard, a consultant for GOP Assemblyman Jeff Miller, who is running against Democrat Richard Roth, an attorney, in a Riverside County Senate district.
A key battleground is in the San Joaquin Valley, where two Stockton residents are facing off: Democratic Assemblywoman Cathleen Galgiani and Republican Assemblyman Bill Berryhill. Registration in the district is evenly divided.
Each candidate has raised about $900,000 for the general election, with significant help from their parties' organizations.
In a district straddling the San Fernando Valley and Ventura County, Democratic Sen. Fran Pavley placed second in the primary to newcomer Todd Zink, a Republican prosecutor for the Los Angeles County district attorney's office.
A group calling itself the California Senior Advocates League PAC has reported spending $315,000 so far to oppose Pavley with mailers and television ads, while putting $228,000 into an independent campaign opposing Galgiani and $90,000 to oppose Roth.
That PAC was funded mostly by a group called the Reform California Now Independent Expenditure Committee. That committee's money came largely from the California Real Estate Independent Expenditure Committee and large contributions from Chevron, cigarette maker Philip Morris and GOP activist Charles Munger Jr.
