FRESNO -- Michael Bumgarner has never walked a precinct in a political campaign.

But his strong opposition to same-sex marriage prompted the retired insurance executive and devout Mormon to join thousands of volunteers going door-to-door in support of a ballot initiative that would ban gay nuptials here.

"I've never stomped before, but I want to be a part of this," Bumgarner said, adding that his late mother would "turn over in her grave" if she knew that gay men and lesbians could marry.

With less than 11 weeks before Election Day, supporters of Proposition 8 are ramping up their field organization and refining their message as they seek to persuade California voters to shut the door on same-sex marriage. It's the first time voters will be asked to weigh in on the issue in any state where gays have already won the right to wed.

An estimated 15,000 backers of the measure, the vast majority of them members of Mormon, Catholic and evangelical Christian churches, knocked on doors and distributed campaign literature to registered voters throughout the state this weekend and last, according to Jennifer Kerns, spokeswoman for the Yes on 8 campaign.

The initiative is a constitutional amendment, similar to ones already enacted in 26 other states, that would overturn the California Supreme Court decision that legalized same-sex marriage.

Ron Prentice, director of the coalition of religious and social conservative groups that qualified the amendment for the November ballot, said the group has ordered 1 million yard signs and 1 million bumper stickers. The plan is for supporters to put up the signs in unison next month, Prentice said.

"Unless the people are angry," Prentice said, "nothing will happen. We are going to change the Constitution and say on Nov. 4, 'Judges, you can't touch this."'

For now, the campaign's goal is to identify its supporters as well as voters who are unaware or haven't made up their minds about the measure, said Al Almendariz, 61, a retired air traffic controller and lifelong Mormon.

Almendariz led a team of five people canvassing a suburban neighborhood southeast of Sacramento on Saturday, and their script was concise.

The volunteers told people who answered their doors they were with the Proposition 8 campaign, an effort that would define marriage as being between a man and a woman. They didn't mention same-sex marriage unless a resident brought it up.

"We're just polling -- yes or no, not trying to find converts or change people's minds," said Christina Hirst, 28, a photographer with three young children. Hirst and her husband, Justin, 33, a high school Spanish teacher, said they joined the door-knocking on Saturday because they don't want their children hearing about gay relationships at school.
