“In conversations with a number of my fellow major No on 8 donors,” Mr. Bohnett said in an e-mail message, “I find that they share my sentiment: namely, that we will step up to the plate — with resources and talent — when the time is right.”

“The only thing worse than losing in 2008,” he added, “would be to lose again in 2010.”

The issue of when to go back to the polls was also the central topic at a contentious “leadership summit” held Saturday at a church in San Bernardino, east of Los Angeles, where about 200 gay rights advocates gathered to discuss their next step. It was the second large meeting of gay leaders since late May when the California Supreme Court ruled against a legal challenge to Proposition 8, which passed with 52 percent of the vote.

Shortly after the court’s decision, officials at Equality California, one of the largest gay rights groups in California, issued an online plea for donations for a possible 2010 campaign, citing a need to capitalize on anger over the decision and on the seeming momentum from the recent legalization of same-sex marriage in several other states.

But that thinking has apparently evolved.
