(CNN)- Meg Whitman's gone where no other California gubernatorial candidate has gone before.
According to new campaign finance records filed Tuesday, Whitman has spent $140.1 million overall on her bid for governor, eclipsing the amount spent on previous gubernatorial elections in the state.
By comparison, all the candidates in the 2006 gubernatorial election spent a combined $40.5 million, while 135 candidates spent a combined $49.9 million in the 2003 gubernatorial recall election. In 2002, gubernatorial candidates spent a combined $107.1 million.
The former eBay CEO herself has donated a total of $119 million to her campaign, more than any candidate has spent in personal funds in a single campaign. The previous record had been held by New York City Mayor Michael Bloomberg, who contributed $108.4 million to his 2009 re-election bid.
"California is an expensive place to run a campaign, but this is still a staggering amount for one candidate to spend on one statewide election," says CNN Political Research Director Robert Yoon. "This is a level of spending you usually only see from major presidential candidates and national party committees."
Whitman has spent approximately $55 million since early June, when she defeated former technology company CEO Steve Poizner in an expensive GOP primary campaign.
"Our campaign has a budget designed for victory and we've invested the necessary resources for success on Election Day. Meg is grateful to the many supporters who have donated and her personal investments ensure as Governor, she will not owe anything to anyone except the people of California," said Sarah Pompei, a Whitman campaign spokeswoman.
California Attorney General Jerry Brown, the Democratic gubernatorial nominee, has spent around $11 million on his campaign, but he didn't face any serious primary challenges and has enjoyed the support of spending by independent groups in his behalf. Groups funded by partially by labor organizations have spent more than $10 million on television commercials attacking Whitman.
Most recent polls of likely voters in California, including a CNN/Time/Opinion Research Corporation survey, indicate that Brown holds a single digit advantage over Whitman.
The winner of November's general election will succeed moderate Republican Gov. Arnold Schwarzenegger, who's prevented by term limits from running for re-election.
