Don't think so.
They can't even get gay marriage passed in IL now (20 black legislators blocked it).
The number of states allowing it has slowed to a crawl and maybe even a full stop.
I think they're going to jump the shark soon with some kind of high-profile headline scandal. I think they're power may have peaked altho the fat lady hasn't sung quite yet.
A state doesn’t have to allow performing gay marriage locally, to accept it and recognize it, and that they all will do.
A legally married Marine and his family and kids will be legal in all 50 states when he is transferred there, or moves there.
