I think Cruz overlooked a gimme on the family history thing. When Trump raised the issue on stage, Cruz should have grinned and said, "Donald, just for the record, my family has been in this country longer than yours. Both of us have one immigrant parent. On the other side, you are the grandson of two people who came over from Germany. On my mother's side, both of my grandparents were born in the USA. Three of my great grandparents are from Ireland and Italy, and one goes back in this country further than that ...."
He could have said something along those lines, joked about wanting to see Donald's boyhood pictures in lederhosen and kilts, and then addressed the foreign birth issue.
