There's no way around it, but Trump's reaction to the Muslim parents who spoke against him at the DNC was ham-fisted, amateurish and a political blunder that he may not be able to recover from in the months leading up to November. And the irony of it all is that Trump blew an easy layup to turn the situation to his advantage.
In this case, an off-the-shelf political response would have served Trump much better than his cringe-worthy knee-jerk reaction and fit of pique. To put the right words in his mouth, "It tells you a lot about Hillary and the Democrats that they chose their convention to use two grieving parents of a murdered American soldier to score points for cheap political gain. Just another example that Hillary's blind ambitions override commonsense, sound judgment and love of country. Really folks, we’ve seen this all before. Is that the kind of person we want to run the United States of America? "
Alas, if only. Too late now.
