Although it does show a flaw in the GOP nomination process, that they need to address.
I am not sure that the system is flawed. It is similar to the electoral college process. In the electoral college, the electors are the real voters, in the same way the the GOP uses delegates.
If you can’t bring your “voters” (delegates) to the “poll” (caucus) then do you deserve to win?
Also, this process has been in place for a long time.
1920: Warren G. Harding shows up with the least number of delegates but still wins nomination after the 10th ballot.
1976: Ronald Reagan used the same stategy that Ron Paul is using today to attempt to “steal” the nomination from Gerald Ford by having more delegates. Ronald Reagan lost, as the establishment considered him “dangerous” and a “kook”. At that time, only four congressmen supported Reagan. Ron Paul was one of those four.
