I don’t think Trump needs to respond from this point beyond asking if Cruz’s blood pressure is OK.
Or ask him if he meant to say ‘as red as the Canadian maple leaf’.
There are good arguments for either Trump or Cruz. For Senator Cruz, the only real issue that he can exploit now is Trump’s total lack of government experience. Of course that seems like a positive to change-hungry voters. But it is a legitimate question to explore before the nomination is settled. Is it really possible, or wise, for the nation to select a president who has never held any kind of high office or demonstrated in that office his real perspectives? And that opens the other door that Cruz should open, namely this — can Trump be trusted to remain as conservative as he proclaims himself to be?
If these questions can be answered in ways positive to Trump then most of us (even ardent Cruz supporters) would have to defer to his momentum and clout and say, full speed ahead, but don’t forget who gave you this mandate and why.
But if there is significant doubt on either question (experience, sincerity) then it becomes Cruz vs Rubio and the fight becomes one about principles vs pragmatism.
That could also raise opportunities for Cruz.
This is not over yet. If Super Tuesday becomes Super Cruz-day then it’s a dogfight to the convention.
I don’t think Trump needs to respond from this point beyond asking if Cruz blood pressure is OK.
If he does that, he wins.
