There is too much bad blood on both sides for a Trump-Cruz ticket to be possible. Not going to happen. No one would have thought a Bush-McCain ticket would have made sense in 2000, considering the hostility that existed between the two camps. And, frankly, the hostility this year is about 10x what it was in 2000.
Hope you are right - that a Trump/Cruz ticket is not possible.
We don’t want to give them anything to create chaos to destroy our winning chance.
