One of the best features of American politics used to be its reliability. I’m not saying it ran well, but at least you knew what the parts did. Democrats tried to increase social services and tax rich people to pay for them. Republicans tried to invade the Middle East and lower taxes to pay for it. The shouting pundits, flacks posing as reporters, vampire consultants and party hacks all shook out along recognizable strategic and political lines. Then 2016 happened. Today is Friday, and the old verities no longer apply. Won’t you try to tell the players without a scorecard with me?
