FILE - In this Wednesday, Oct. 31, 2012 file photo, Sen. Claire McCaskell, D-Mo., speaks to the media outside Bayless Elementary School, in St. Louis County, Mo. McCaskill says she now believes that gay couples should be allowed to marry, a change from her previously nuanced stance during her 2012 re-election campaign in which she defended the right of Missouri voters to outlaw same-sex weddings.
