Read into this what you will, but I think there's room to find encouragement, from Lyle Denniston at scotusblog
The Supreme Court, in a one-sentence order without explanation, refused on Wednesday afternoon to stop same-sex marriages in Oregon. The denial was by the full Court, after Justice Anthony M. Kennedy had submitted the plea to it.
The request had come from a private group that is strongly opposed to same-sex marriage, the National Organization for Marriage. It had been barred from taking part in the case over the constitutionality of an Oregon ban, and it had asked the Justices to put off a judge’s decision striking down that ban.
Oregon's ban on marriage came in a constitutional amendment passed in 2004, just as Arkansas's did. A 2013 lawsuit produced a federal judge's ruling that the amendment was unconstitutional, just as Circuit Judge Chris Piazza has ruled in Arkansas. An anti-gay group asked the 9th Circuit Court of Appeals for a stay of the ruling, just as anti-gay forces are seeking from the Arkansas Supreme Court. The 9th Circuit refused. And now the U.S. Supreme Court has refused, too. In Oregon, a petition campaign is underway for a ballot initiative to overturn the amendment.
