I know his strategy. Even if it were successful, it makes no sense. The nomination of a deeply divided party would ensure defeat in November. Why is he still in the race? Why is Kasich still in the race? They are both nut cases on an ego trip.
Because Cruz is being supported by the GOPE, and the GOPE would rather see President Hillary than allow Trump to win.
It makes sense once you view the Dems and the GOPE as just branches of the Oligarchy.
