Arnold Schwarzenegger entered the last full day of campaigning for the governorship of California as a poll showed his support slipping and more women surfaced to accuse the actor of groping them.

　　Governor gray Davis said Schwarzenegger owes a full explanation before voters decide today whether to recall a sitting governor for the second time in the nation's history.

　　Schwarzenegger, who continued to blame the widening scandal on political dirty tricks, said he wouldn't say anything more about sexual harassment claims, now made by a total of 15 women, until after the election.

　　"I can get into all of the specifics and find out what is really going on," he said on Sunday night. "But right now I'm just really occupied with the campaign."

　　With polls showing the race tightening, Davis said on Sunday that Schwarzenegger "is in sort of a free fall" and could be overtaken in the closing hours of the campaign.

　　Davis also used the power of incumbency to create news on Sunday, signing a law making California the largest state to require employer-paid health care for an estimated nearly 1.1 million working Californians currently without job-based coverage.

　　The Los Angeles Times reported that four additional women claimed Schwarzenegger touched them inappropriately. They included an unidentified 51-year-old woman who said Schwarzenegger pinned her to him and spanked her repeatedly three years ago at a West Los Angeles post-production studio.

　　Three other women named by the Times said Schwarzenegger fondled them in separate incidents outside a Venice, California, gym in the mid 1980s, at a bar in the late 1970s and on the set of the movie "Predator" in 1986.

　　Schwarzenegger spokesman Sean Walsh dismissed the accounts of three of the women, and said the actor had no recollection of the alleged gym incident.

　　Schwarzenegger did not address the allegations during a march to the state capitol on Sunday. Davis "has terminated opportunities and now it's time to terminate him," Schwarzenegger said before addressing a Capitol rally crowd of nearly 5,000.

　　Democratic attorney General Bill Lockyer said Schwarzenegger should volunteer for a state investigation, whether or not he is elected governor.

　　Lockyer noted the one-year statute of limitations for sexual battery has expired on all the complaints that have surfaced since the Times reported on Thursday that several women claimed Schwarzenegger groped or sexually harassed them between 1975 and 2000.

　　Schwarzenegger spokesman Rob Stutzman accused Lockyer of engaging in the sort of "puke politics" the attorney general had earlier warned Davis to avoid.

　　A poll released late on Saturday found support for recalling Davis might be slipping, although 54 percent favored removing him while 41 percent were opposed.

　　The poll, conducted Wednesday through Saturday, found the percentage of people saying they would definitely vote to oust Davis dropped in the last days the survey was conducted, from 52 percent on Wednesday to 44 percent on Saturday.

　　The poll also indicates the race tightening between Schwarzenegger and Lieutenant Governor Cruz Bustamante, the leading Democrat among the replacement candidates.

　　The poll showed Schwarzenegger with 36 percent support, to 29 percent for Bustamante. A poll conducted by the Field Research Corp between September 25 and October 1 gave Schwarzenegger a 10-point lead over Bustamante.
