A Former GOP Mastermind Is Now Fighting to Save Gay Marriage and Unmask the Mormon Church

But then, in midsummer, Karger noticed something new. Suddenly, money started pouring in to ProtectMarriage.com, and by August, the group was raising about $500,000 a day. Karger wondered where all the money was coming from. Most of the donors, he soon realized, had never made a political contribution before. Some had given to just one candidate: Mitt Romney. Quite a few were graduates of Brigham Young University. It wasn't hard to connect the dots: This was Mormon money.

Once he knew what to look for, Karger found Mormons everywhere in the Prop 8 campaign: as actors in the TV ads, as volunteers, organizers, and political consultants. Just as intriguing, he would discover eventually, the group that had done the lion's share of the work to get Prop 8 on the ballot to begin with, the National Organization for Marriage (NOM), also had deep ties to the Mormon Church—and the church itself had been engaged in a campaign to block gay marriage across the nation for more than a decade. What he was looking at, he realized, was a stealth campaign much like the ones he'd run during his long career as a Republican political operative.

As a political professional, Karger—who for decades worked for one of California's premier campaign consulting firms, a shop that had helped invent modern opposition research—was grudgingly impressed with what the Mormons were doing. "They completely altered the landscape," he says. "They took over every aspect of the campaign." Karger estimates that Mormons ultimately contributed $30 million of the $42 million total raised in support of Prop 8, which passed easily in November 2008. (By contrast, anti-Prop 8 forces raised $64 million.)

But if the opponents of gay marriage won the battle, they also ensured themselves a big headache. In Karger, they galvanized an adversary who has now dug in to fight for the long haul—and who brings a dramatically different skill set than the rest of the marriage-equality movement. As Karger notes, most of the prominent gay-marriage advocates are, well, married people: risk averse and unschooled in the political dark arts. "I'm a different kind of gay activist," he says. "I'm a little wilder."
