According to Tim Kincaid at Box Turtle Bulletin, an anti-gay marriage amendment to the Pennsylvania constitution submitted by state Senator John H. Eichelberger, Jr. died in the Judiciary Committee.
Tim says:
But there was no debate whatsoever on the bill, so we can only speculate about possible motivations. It may well be that these Senators have come to know and love gay people in their lives. They may have found a new respect for equality.
I hope so.
