At a $10 million disadvantage and trailing five points in the polls, gay marriage proponents in California rolled up their sleeves and went to work. That was two weeks ago. Since then the campaign has focused their wobbly ads, enjoyed a cash infusion, and managed to close in on their opponent's lead to within spitting distance.

A new CBS/SurveyUSA poll released Friday shows gay marriage backers narrowing the gay marriage race to only three points. The poll of 615 likely California voters found that 48 percent favored Proposition 8 – the November 4th initiative that seeks to ban gay marriage in the state once more – while 45 percent were against it.

The No-On-8 campaign's good news is likely due to changes in the tone of the campaign, celebrity endorsements and an increase in donations to the campaign.

While anti-gay marriage ads played on voter's fears about what gay marriage means for the Sunshine State – children being taught gay marriage in public schools and churches loosing their tax exemptions – a sleepy narrative on the pro gay marriage side pleaded with undecided voters to remain fair and not allow Prop. 8 to take away rights from gays and lesbians.

The limp-wristed ads failed and polls quickly turned on the once-leading pro gay marriage camp.

But the ads were replaced last week and the campaign's tone sharpened considerably. The new ads directly respond to the false accusations offered by the Yes-On-8 campaign.

“Their attacks have come before and they always use the same scare tactics,” an announcer says as Yes-On-8 ads are displayed in television screens. “This time they want to eliminate rights and they're using lies to persuade you. Prop. 8 will not affect church tax status. That's a lie. And it will not effect teaching in schools. Another lie. It's time to shut down the scare tactics.”

After, the principle backer of the gay marriage ban, announced they were at a $10 million advantage, pro gay donations increased considerably – $5 million in the last week alone – leveling the the field once more.

And celebrities continue to provide inspiration and sustenance to gay marriage proponents: Director Steven Spielberg and Hollywood actor Brad Pitt each donated $100,000 to the campaign.

Comedienne/chat show host Ellen DeGegenes has announced plans to spend $100,000 of her money to buy TV airtime for her own commercial against Prop. 8. DeGegenes's own September marriage to actress Portia de Rossi is at peril should the the ban win approval.

Margaret Cho and Molly Ringwald are among the celebrities endorsing gay marriage in new ads playing on the Internet. The clever ads lampoon Apple's “Mac v. PC” marketing to address the issue of gay marriage with humor.

With only 15 days left before the polls open, gay marriage backers have managed to change the rules in the Prop. 8 race, but with time running low can gay marriage in California be saved?
