Yes this writer gets it, and except for an excessive belief in the current polls showing Bernie and Hillary beat Trump in November the article is valid.
Interesting fact: NEVER in the history of the GOP has a candidate reached the convention with 90% of the needed delegates and failed to receive the nomination. Trump will easily attain that goal, and may reach the 1237 before the convention, but the fact is, assuming he gets to 90% it would literally be unprecedented to deny him the nomination.
