Another attempt to stay a judge’s decision allowing same-sex marriage in Oregon.     The National Organization for Marriage has asked the U.S. Supreme Court to stay a federal judge’s ruling overturning Oregon’s one-man, one-woman marriage law. NOM Chairman John Eastman says they’re not sure when to expect a response.    The NOM request was filed Tuesday with Justice Anthony Kennedy. U.S. District Judge Michael McShane in Eugene ordered last week that same-sex couples be allowed to marry.
