A likely strategy all along was that Cochran wins, then steps down, then the GOP appoints Barbour to run in the general election without having had to run in a bruising primary.
However, all heck will break loose if Cochran resigns and the party does not appoint McDaniel as the replacement. Not only did McDaniel win the primary, he's also a respectable two-term sitting state Senator.
