Kasich will probably just not go then. He has little to lose. There is no great wellspring of enthusiasm for John, never has been, except from the left. Ted Cruz, has plan for the future, and after some fake coyness, some public hemming and hawing, Ted is likely to decide that yes, he will endorse.
I doubt if Carly goes. Her stock price dropped straight down through that strategically placed trapdoor. If Trump wins, I can see using Carly then in some capacity. All kidding aside, she has lots of inner strength and confidence.
Ohh but that FACE! Please, no! :(
