As if Trump is just going to stand there and take it.
However, if they nominate Cruz, he'll take it and presumably his voters will vote for him and split the Republican vote. Boom, President Hillary. This can't happen.
It saddens me to say that if the GOPe tries to push Trump out, Cruz must leave with him and form a coalition ticket as Trump's VP. I have been dismayed by the Trump campaign for some time but am becoming so with Cruz as well. I think his ambition in such a brokered convention would not let him see that Trump's voters will not leave ever and would not unite under the party banner. Where Trump goes, they go. Forever.
Again, President Hillary. I think the GOPe is fine with that.
