Regardless of what Curly said or how it may have been taken out of context, he has no major influence with the RNC.
At the Spring Convention Meeting held last week, the RNC stated emphatically that whomever first got to 1237 would be the nominee.
But, in a recent statement, the GOP party chairman said if Trump falls just one vote short (1236) that he will not be the nominee.
As this ND guy pointed out, there are a lot of rules-games that can be played with even so called bound/committed delegates to unbound & uncommit them.
