And I ask this question of you as well then- If the party is going to ignore delegate count to steal away the nomination from the rightful candidate, why would they turn around and give their support to someone that the party despises, and someone who is also capable of alienating the national electorate?
There is also a possibility that somebody other than Cruz becomes the nominee. But I see that as remote, even less of a chance than Trump or Cruz being the nominee. There is already a legitimacy problem with nominating somebody other than the person who has obtained the most delegates. To further add to that problem by nominating somebody who has obtained few to no votes at all would be too much, in my opinion. Legitimacy is not a binary variable, I'd argue, there is a sliding scale of legitimacy based on electability and who represents the will of the GOP electorate.
The clear choices in such a scenario would be:
1) Somebody who has obtained some delegates, but a minority (Kasich, Rubio)
-I can't see somebody making a strong case for either. They ran and lost, and there isn't much evidence that they have enough support to be a nominee, especially since they have proven they can't run a nationwide race.
2) Somebody who was not running, but has a strong presence within the party and national recognition. Somebody who has run for President before, probably(Romney, Ryan... somebody else?)
-I would argue that this would be seen as the Washington Elite pretty much stealing the race, so unreasonable. I actually think this is more possible than (1) though.
Based on this, I think Cruz is the only person who occupies the nexus of: Not Trump, but could be seen as an a viable alternative. He has run a national campaign and has succeeded (somewhat) in running it. He has amassed enough delegates that he could be seen as the will of (some) people. Unfortunately he's not liked by many in the party, but you've already seen them coalesce around him to some degree (see Lindsey Graham as an example of that).
