A group of anti-gay marriage Christian conservatives are campaigning to replace four Democratic judges with like-minded social conservatives in California where judges are directly elected, the AP reported.

The group called Better Courts Now was founded by Don Hamer, a San Diego pastor who opposed gay marriage before he died of a heart attack in March. Hamer campaigned in favor of Proposition 8, the 2008 voter-approved initiative that trumped a state Supreme Court ruling that legalized gay marriage in the state.

Dr. Jennifer Morse, founder and president of the Ruth Institute in San Marcos, a group affiliated with the National Organization for Marriage (NOM), the nation's most vociferous opponent of gay marriage, is among the 20 video testimonials that appear on the group's website.

I “encourage you to join me in supporting local judicial candidates who take a strong stand for traditional values,” Morse says.

The group is working to unseat four San Diego Superior Court judges and replace them with its slate of socially conservative candidates.

“We believe our country is under assault and needs Christian values,” said Craig Candelore, one of the candidates. “Unfortunately, God has called upon us to do this only with the judiciary.”

The group says it wants to make judges more accountable to the public: “BCN is standing for accountability, boundaries and common sense for judges in San Diego county,” the group says on its website.

Critics say the group's campaign threatens the court's separation of church and state.

Also supporting the group with video testimonials are Jim Garlow, lead pastor of Skyline Church in San Diego County, who took a leadership role in the campaign to ban gay marriage in California, and Ron Prentice, chairman of the Yes on Proposition 8 campaign.

A Better Courts Now Facebook page has attracted 1,366 people as of Sunday.

San Diego voters head to the polls on June 8.
