... Last year, the Iowa Supreme Court upheld a lower court's ruling that the state's law barring the recognition of same-sex marriage violated the Iowa Constitution. It was a major victory for gay rights groups, in part because Iowa is the only Midwestern state to allow same-sex couples to legally wed, joining four other states and the District of Columbia.
Supporters note that ousting the judges would not change the ruling. Nevertheless, they see it as a symbolic threat and have begun reaching out to voters.
