well with Trump and kasich people combining he would have a majority..
A majority is really pretty useless if they have nothing to vote on, as I understand it, changes have to come out of a rules committee, controlled by the GOPe, before any delegates could vote on it, so the premise of Trump and kasick making a backroom deal to exclude Cruz is moot.
And how would that backroom deal between Trump and kasick be less abhorrent than the way Trump supporters feel about Cruz working within the rules to have delegates commit to him if they become unbound? Oh yeah it's because.......Cruz!
