"George W. Bush, that defender of democracy and the new world, is known to split hairs when it comes to issues ranging from energy consumption to the war in Iraq. But now it seems he has taken his calling literally." What is the meaning of "Calling" in the above. From the context, I can make out the meaning as "occupation" but which occupation the writer is trying to convey. Is it "hair splitting" ?
