Robbie the contests in Colorado and Wyoming were both repugnant. As word has gotten out about the corruption of the leadership and how the process was handled the GOP has been damaged. No amount of equivocating can make it right. I am not blaming Cruz, Kasich or Trump, this was a failure that has stained the party leadership.
I know very well how the process works having been involved in local politics, as a volunteer myself. And yes my fellow Republicans are mostly very decent people. The people that I have problems with are the lawyers who all seem to believe that they are more important than everyone else regardless of their actual accomplishments. They are mostly despicable on so many levels and unfortunately do make up a sizable percentage of the leadership.
It is self-serving for Trump to complain about corruption simply because the state party in those two states preferred another candidate over him. I am sure they would rather have had a Bush or Rubio to vote for. Trumps problem is that despite his successes his numbers was not great enough to force them to accept him as inevitable and he is widely portrayed, true or not, as even less electable than Cruz. When the rule was struck, the intent was to bolster the size of the front runners-lead. That was not supposed to be any of the three men still in the race. Now Trump is the only one who has a chance to reach the magical number of delegates with his victory in NY. Even though he gathered about half the support that Hillary did in her primary and two-thirds that of Bernie, Cruzs vote was humiliatingly low. There will be tendency to stop the effort to stop Trump from getting what he needs to win on the first ballot, because his support is soft, both in the party and in the nation. I fear that we are back to 1964, not because the Democrat candidate is near as strong as Johnson was in 1964, but because the need to prop her up is very strong among the National establishment.
