There are a few things that will get LDS Church members to open up their pocketbooks: a Mormon presidential candidate, tithing and gay marriage.

Church members, mostly from California, have made individual donations close to $5 million in support of Proposition 8, counting only donations of more than $1,000, according to one Web site. The proposition is on the November ballot and would change the state's constitution to allow for marriage only between a man and a woman.

Gay marriage has been legal in California since earlier this year, when the state Supreme Court ruled against a state ban on same sex marriage in a 4-3 decision. The ban was passed in a 2000 voter referendum.

In June, California church authorities read a statement from Salt Lake City leaders over the pulpit that church members "do all [they] can to support the proposed constitutional amendment."

That has resulted in a mass of donations, said Nadine Hansen, who runs the Web site MormonsFor8.com. The site has a spreadsheet that shows donors in favor of Proposition 8 who have given more than $1,000. Such donations have to be reported immediately and are thus updated every night.

"I suspect that when this is done, probably 80 percent of the money [from individuals] will be from Mormons," said Hansen, who describes her site as a neutral place to simply show who is donating. So far, the numbers show it's closer to 30 percent, but many areas have yet to report and many small donors haven't been catalogued yet.

Figuring out who is a member of the LDS Church has been a patchwork effort. Some names are well known, but others have been found through blogs, neighbors and even donors themselves.

"We didn't know what kind of information we were going to get," Hansen said. "But we seem to be getting some very honest information from people."

LDS Church spokesman Scott Trotter said Monday that donor questions should be directed to ProtectMarriage, a coalition trying to pass the proposition. Coalition spokeswoman Jennifer Kerns said the church has played a significant role in support of the proposition, but that the coalition does not keep track of donors' religions.

There have also been 25,000 volunteers going door to door each weekend to inform voters about their point of view.

"A good portion of those have been from the LDS Church," Kerns said.

Church leaders have said they do not object "to rights already established in California regarding hospitalization and medical care, fair housing and employment rights, or probate rights, so long as these do not infringe on the integrity of the family or the constitutional rights of churches and their adherents to administer and practice their religion free from government interference."

Hansen is LDS, though she won't say what side of the proposition she comes down on, only that her site is intended to be neutral. She lives in Utah but is a native Californian and still has family there.

"We've had people from both sides think we are on the opposite side they are on," she said.

There are a handful of Utah County residents on the donor list, though not all in favor of the proposition. Gay advocate and WordPerfect founder Bruce Bastian said he was going to donate $1 million to fight Prop 8.

"One thing I learned as a Mormon was that preaching costs money," Bastian was quoted as saying in the San Francisco Chronicle. "The Mormons will raise a lot of money to support Proposition 8 in November."
