It would appear that Cruz wants to go it alone.
I think that the two of them would have been unstoppable.
Well, the problem with that (what I used to think was a great) idea, is that Cruz supporters are rabidly against Trump (compare Trump to Hitler, here on FR, for example).
So, Cruz likely knows that his supporters don’t want to have anything to with Trump.
Cruz’s loss, imo.
Once bitten . . .Santorum's a great example. He got close enough to feel the glow last time and can't give it up now.
