California Republican Meg Whitman has set a new record for self-financing a campaign.

The former eBay CEO added another $15 million to her gubernatorial bid on Wednesday, bringing her total contribution to just over $119 million, according to the Sacramento Bee

Whitman has now outpaced the spending record set by New York Mayor Michael Bloomberg, who burned through some $110 million of his own fortune winning a third term in 2009. 

Despite Whitman's investment, a recent CNN/Time poll conducted Sept. 2-7 showed Whitman leading Democrat Jerry Brown in November 48 percent to 46 percent, but that fell within the polls margin of error. 

Republicans are banking on Whitman’s massive outlay boosting their prospects in the Golden State's Senate and House races. 

"Governors' races drive turnout," Mississippi Gov. Haley Barbour, who heads the Republican Governors Association (RGA), said during a recent trip to Washington. "Usually, governors’ races are better funded, and they take a lot of the responsibility in the ground game."

On the Senate side in California, Sen. Barbara Boxer (D) is being challenged by Republican Carly Fiorina.

"There is a correlation between electing senators and electing governors," Barbour noted. "It is a very high likelihood that if we don’t elect a Republican governor in a state, that we will not pick up a Senate seat. That rarely happens; in the last 20 years, it’s rarely happened. Those two are tied together — a lot."
