The Principal Enemy
Back in the seventies when I was a lefty and under the sway, like the new mayor of the city of New York, of various Central and South American marxists, we used to speak of "el enemigo principal," the principal enemy. In fact, there was a rather graphic (and well made) Bolivian movie of that name by leftwing director Jorge Sanjines. (Clip here.)
Not surprisingly in those days the principal enemies of Sanjines' film were los yanquis and their dreaded CIA -- a bit of a cliché, one must admit, but the idea of having a principal enemy in itself is not bad, if you know who it really is. Identifying your enemy can make you more effective, whoever you are.
And, whether they know it or not, Republicans, conservatives, libertarians, center-right folks, all those who favor smaller government and increased freedom, do have a principal enemy. But, surprisingly, it's no longer Barack Obama. He is over. He was already a lame duck when Obamacare plucked most of his remaining feathers. The damage he can do may still be serious, but most of it will be reparable.
