Because, unlike you establishment jackboot lickers, Trump is tired of the same old milquetoast, backstabbing establishment way of doing things and is standing up to them.
If Trump has such a problem with the rules does it dawn on anyone he should have addressed those issues at the beginning of the process instead of when it looks like things might not work in his favor.Are you people aware that Cruz and Trump are in control of any rule changes prior to the start of the convention?.......that is why Kasich will never get a chance at a floor vote.
