You have to take his comment in full context and not read something into it by the headline. The Democrat controlled state capital passed gay marriage with the Governor signing it. We Washington voters are saying, wait just one cotton picking minute, you cant do that without us state citizens having a chance to have our say in a general election. If enough signatures are gathered, gay marriage will be on the November ballot. If the voters say NO, the law is dead. It should be the citizens not Olympia deciding something as controversial as this. That is what Newt is saying, and you can bet at the Newt rally and any Republican rally, there will be plenty of signature gatherers.
If that is the case, then what is the point of have a representative government? Why not just have state referendums on every issue?
