Something tells me that BOTH Trump and Cruz are very ware of the others expertise and abilities.
Example: Cruz has plead NINE DIFFERENT CASES before the United States Supreme Court.
He WON ALL NINE of those cases.
As a debater of significant stature Cruz is exceptional at getting people to see his POV.
Cruz, in turn, can see Trump's strengths.
To SMART street=wise guys should have sense enough not to fight one another but work together using one another.
Time will tell. We shall see.
Looks as if you got your wish. It appears Trump and Cruz are teaming up to take on Washington very soon over this Iran Deal.
