AP: Stunned and angry, national gay rights leaders Wednesday blamed scare-mongering ads - and President Barack Obama's lack of engagement - for a bitter election setback in Maine that could alter the dynamics for both sides in the gay-marriage debate... Gay activists were frustrated that Obama, who insists he staunchly supports their overall civil rights agenda, didn't speak out forcefully in defense of Maine's marriage law before Tuesday's referendum. The law was repealed in a vote of 53 percent to 47 percent.
