I do not agree.
If there is a second ballot, the entire establishment will be for someone like Romney.
They are only for Cruz as long as he is the one who can oppose Trump. They will completely abandon him, if there is a runoff.
Neither one will win.
I think Cruz will instill enough loyalty to hold his delegates past the first ballot and I think he can grab enough delegates from the candidates who suspended and even Trump to get the 1,237. Trump seems to think his dialog with delegates is over and shows that he is an amateur at politics. I think someone like Walker will be put in nomination before a 3rd ballot if Cruz fails.
The 2000 some odd Cruz and Trump delegates will immediately become establishment delegates? I think Cruz could hold most of his delegates while picking some up.
Who is going to put this magic candidate into nomination? If he can reconcile the Cruz and Trump delegates immediately then he deserves the nomination. I don't buy the notion that the Trump and Cruz delegates are stealth establishment delegates. Paranoia runs rampant.
