Is Nate Silver handicapping who will come out in favor of gay marriage next? Hillary Clinton released a video online Monday saying she supports gay marriage. Clinton says “LGBT Americans” are “full and equal citizens and deserve the rights of citizenship, and that includes marriage.” The move comes just days after Ohio Republican Sen. Rob Portman declared his support for gay marriage, saying his position had changed due to his gay son. It also comes shortly after former president Bill Clinton called for the repeal of the controversial legislation he signed, the Defense Against Marriage Act, which he said is unconstitutional. Several key Democratic contenders for 2016 have thrown their support behind gay marriage as well.
