Might want to study up on Trump’s character, hes not sneaky like that, if he wants to damage he gets in your face and does it himself. Cruz is sneaky, most professional politicians are sneaky. Trump is very direct.
That we know of.
Of course I imagine he was being a bit sneaky when he slept around with all those married women he bragged about.
I imagine he will do whatever is needed.
Donald Trump hates to lose.
