The system is not rigged and Trump knows it is not. Trump did better in the last set of primaries than was predicted. None of these states, except Pennsylvania can possibly go to Hillary in the fall. Cruz did worse because the liberals in these states could vote for Kasich to show how much they dislike Cruz. I dare say that no matter how the Convention votes, if it were a free convention, Cruz would win. Back in 1976, the majority of delegates preferred Reagan, but Ford was able to persuade several delegates he was going to win so they had better get on the train. Distinguish the delegate from the leadership. To a man they hate Cruz more than they do Trump, or Hillary for that matter. To his advantage, they think that Trump can be managed. That he is an old if highly energetic old man counts in his favor. That he is unpredictable counts against him.
You are wrong so many levels
I hope you are not part of the ever trump crowd
