Something important is being missed in never-ending saturation coverage of Donald Trump's rather modest war of words with the Khan family. The storyline is so perfect for the liberal media - horrible Republican nominee insults parents of dead servicemen - it's rather astonishing how few recognize what an ambush this whole thing was.
It's long been a Democrat tactic to hide behind the skirts of people they declare to have "absolute moral authority," meaning that they can never be criticized for anything no matter what they say or do. You will remember this was the status bestowed upon insane Bush critic Cindy Sheehan. Because her son had died in the war, she had "absolute moral authority" to say anything she wanted about Bush - no matter how unhinged or divorced from reality. And that made her extremely useful to Democrats, who preferred not to personally impugn the war effort when they could get the mother of a dead soldier to do it for them.
