Judging from the howls of frustrated Democrats you’d think winged monkeys were filling the skies, infants were hurling fireballs from their eyes, and the inaugural procession will be headed by the Four Horsemen of the Apocalypse. Such is their dismay over the election of Donald Trump. I understand. It’s been a long time since their party has been at such a disadvantage, the president-elect is making a national sport out of mocking their worries, he’s spurring international unrest and domestic apoplexy with his free-wheeling Tweets, and aside from organizing protests in the rain Dems don’t seem to know what to do about it. The answer: relax. Smoke ‘em if you’ve got ‘em. (Which, btw, could be easy on Inauguration Day when one pro-marijuana group plans to hand out thousands of free joints.) While he might actually trigger some sort of organic upheaval here or abroad, odds are the overwhelming majority of us — of all religions, creeds and colors — will not feel any real impact at least not any time soon. Why? Oh sure, he says things that drive his critics insane and he’ll pushsome legislation which will infuriate them. Some. But history and the realities of D.C.’s power structure tell us for all of Mr. Trump’s bombast, he is unlikely to produce the monumental changes for which his fans hope — or the cataclysms his foes fear.
