The dilemma Trump faces is how does he defeat Political Correctness if he gives into it yet, at the same time, how can he not give the media a target rich environment if he continues to speak the unvarnished truth.
I suggest the answer is, in part, that the GOP has to unify behind Trump and join the battle.
They had the opportunity to join Trump on the Khazr Khan kerfuffle but betrayed him stating as Newt did that Trump should not have picked a fight with Khan (Khan picked the fight, not Trump). Others have said that Gold Star Families are simply off limits.
If they are off limits, they shouldn't be trotted out by the DNC to join the fight. If they do join the fight, they void their "off limits" status.
If, if, if . . . the gold standard is the truth, the whole truth, and nothing but the truth, across the board, not leaning heavily on showmanship glazing. Trump has been taking it rather lightly, and as a joke. He needs to read Rudyard Kipling's "IF" poem. And writers Simonizing his public image would well do to meditate on that also, IMHO.
