GOVERNOR : Wilson, Brown Set State Record for Fund Raising : The two candidates have collected more than $47.5 million in contributions. Republican incumbent continues to raise more than his Democratic opponent.

Pete Wilson and Kathleen Brown have set a record in the amount of campaign money collected in a race for governor, according to preliminary finance reports from the candidates.

Between them, the Republican incumbent and the Democratic challenger have raised $47.5 million over the past two years--with Wilson collecting $26.8 million compared to $20.7 million for Brown. The figures, released Thursday, do not include several million more expected to be reported by the end of the campaign.

In 1990, the two leading candidates for the office--Wilson, then a U.S. senator, and his Democratic opponent, Dianne Feinstein, collected a total of $45 million in their pursuit of the office, according to figures compiled by California Common Cause. The amounts raised and spent in that race far exceeded any previous governor’s campaign in California history and, by one measure, more than any gubernatorial contest in the country.

According to the Council of State Governments, the 1990 California race--counting all candidates’ campaigns--was the most expensive race for governor in the United States up to that time.

In the latest campaign filings in the California race, which covered the Oct. 1 to Oct. 22 period, Wilson continued to show his ability to raise more than state Treasurer Brown, collecting $3.9 million to her $2.4 million. At the end of the period, Wilson had $1.7 million on hand compared to $533,000 for Brown.

A spokesman for the Brown campaign said it was expected that Wilson as the incumbent would raise more. “We believe we will continue to be competitive financially until the election,” said Brown campaign spokesman John Whitehurst.

Wilson aides, with their candidate leading in opinion polls, are pleased to be ahead on the money-raising side of their contest. “We’re right on track for where we want to be,” Wilson aide Dan Schnur said.
