Mitt Romney, as a Republican governor in 2004, said it's the job of the legislature, not the courts, to decide marriage equality. He repeated that claim this year when a judge in Iowa struck down that state's ban on same-sex marriage.
Conversely, Arnold Schwarzenegger, also a Republican governor, has said in both 2005 and 2007 that it's the job of the courts, not the legislature, to decide marriage equality.
They can't both be right.
