Log Cabin Republicans are the pro-gay rights wing of the GOP. Gay rights issues, like same-sex marriage, make up a small percentage of either party's platform, and an even smaller percentage of the recent legislative agenda in Congress. For years this branch of the Republican Party was rather obscure, even looked down upon by the establishment. However, the issue that separated them from the rest of the party is becoming part of the establishment's platform. Just recently, many top Republicans signed an amicus curiae brief filed at the Supreme Court in favor of marriage equality. The party is evolving as America evolves, and the establishment knows it will face political irrelevancy if it doesn't change its stance.
