Sandra Day O'Connor is not my fave Supreme Court Justice ever, but I'd gladly take her back in exchange for Scalia or Roberts or Thomas considering how reasonable she usually is. (Not always!) Case in point, she's speaking out against moving from merit-based to election-based selection of judges in Iowa, and she also made this remark:
"As Iowa goes, so goes the nation, and I wish the rest of the nation would hurry up and go."
Marriage-equality reference? Maybe not. But definitely an endorsement of the way things are currently run in Iowa.
