I wouldn't be too sure. He remarked early on in his campaign that losing in the primaries was no big deal as he would win in the general. The fix was in back then. IMHO it is still in. They are just deciding as to how to implement it at GOPe.
Jeb may have believed that early on in the campaign when he thought he'd get a sizeable number of delegates and stay in the race until the very end, but there's no way that guy is going to be the nominee after his miserable showing in the early primaries. You don't nominate a candidate who gets less than 10% of the votes in his own political party despite (or because of) a high degree of name recognition.
