American Unity PAC was formed last year to lend financial support to Republicans who bucked the party's long-standing opposition to gay marriage. Its founders are launching a new lobbying organization, American Unity Fund, and already have spent more than $250,000 in Minnesota, where the legislature could vote on the issue as early as next week.
Billionaire hedge fund manager and Republican donor Paul Singer launched American Unity PAC. The lobbying effort is the next phase as the push for gay marriage spreads to more states, spokesman Jeff Cook-McCormac said.
"What you have is this network of influential Republicans who really want to see the party embrace the freedom to marry, and believe it's not only the right thing for the country but also good politics," Cook-McCormac said.
In Minnesota, money has gone to state groups that are lobbying Republican lawmakers and for polling on gay marriage in a handful of suburban districts held by Republicans. So far, only one Minnesota Republican lawmaker has committed to voting to legalize gay marriage: Sen. Branden Petersen, of Andover.
Part of American Unity PAC's original mission was to spend money on behalf of Republican gay marriage supporters. Many GOP lawmakers have faced primary challenges funded in part by anti-gay marriage groups such as the National Organization for Marriage, which argue that the lawmakers had betrayed the party's core principles.
Since forming the lobbying group last month, American Unity also spent money to win over Republican lawmakers in Rhode Island, where last week all five Republicans in the state senate jumped on the gay marriage bandwagon.
Rhode Island is on track to legalize gay marriage by next week, which would make it the 11th U.S. state where gay marriage is legal.
There are also plans to lobby federal lawmakers on gay rights issues.
"We intend to work on this effort until every American citizen is treated equally under the law," Cook-McCormac said.
Other wealthy, traditionally Republican donors giving money to the group include Seth Klarman, David Herro and Cliff Asness.
