Mike Hubbard Won't Seek Demotion in 2014

Speaker of the Alabama House Mike Hubbard (R) won't run for governor in 2014.  He doesn't need to.  He's already de facto King of Alabama, running the state.

Republican Governor Robert Bentley is a weak figurehead, giving Hubbard all the space he needs to sit behind the curtain and work the levers of power. 

Key lawmakers said that there is a disconnect between Bentley and the Alabama Legislature right now, and that Bentley is not having the legislative success expected of a governor who is a former House of Representatives member and dealing with a supermajority of his own party.

Hubbard is sitting pretty in the Leg., cracking the whip on his supermajority and ramming through pretty much any legislation he wants.  And if the Governor objects, tough beans. 

Given all that, why would Mike Hubbard ask for a demotion to governor?
