Trump well ahead, and all the establshment figures tightly bunched. Too close for any of them to want to drop out.
They'll continue to drain the GOPe coffers.
The very best alternative is a +40% Trump landslide that kills off everyone else so he can focus on Hillary and down-ballot races. But this is second best.
With all the establishment candidates still in the race, there is no other outcome than Trump winning. The three establishment candidates continue to split any meaningful vote.
