I very much doubt that Senator King would ever give Republicans control of the Senate, John, as opposed to joining a clear GOP majority. He seems more comfortable ideologically with the Democrats, for one thing. For another, the 2016 Senate-race map looks a lot less friendly to Republicans than the 2014 map. King would have to factor in the possibility that a 50-seat-plus-him Republican majority would disappear after two years, and that he might not have much bargaining power with annoyed Democrats in 2017.
