Did something just go "click?"

During the Vietnam War, American soldiers and Marines encountered something called the "Bouncing Betty," a hidden anti-personnel mine that, when triggered, suddenly "bounced" up to waist height and exploded. The effects were lethal. Donald Trump might be triggering the political equivalent. Per POLITICO, Trump wandered into a racial minefield with this line: "I have a great relationship with the blacks. I've always had a great relationship with the blacks," he said, continuing to call the overwhelming black support for President Obama "very, very frightening." Something tells me Trump's relations with "the blacks" is about to take a "Bouncing Betty" turn for the worse.
