Some hair on it

Obama, in David Remnick’s New Yorker article:

I have yet to see something that we’ve done, or any President has done, that was really important and good, that did not involve some mess and some strong-arming and some shading of how it was initially talked about to a particular member of the legislature who you needed a vote from.

Because, if you’re doing big, hard things, then there is going to be some hair on it—there’s going to be some aspects of it that aren’t clean and neat and immediately elicit applause from everybody. And so the nature of not only politics but, I think, social change of any sort is that it doesn’t move in a straight line, and that those who are most successful typically are tacking like a sailor toward a particular direction but have to take into account winds and currents and occasionally the lack of any wind, so that you’re just sitting there for a while, and sometimes you’re being blown all over the place.”
