Any bill that is that important and that uncontroversial has got a lot of political potential energy. And that means that politicians can take some of that lack-of-opposition, add some pork, and wind up with a personal benefit and a slightly-less-unopposed bill.<p>The end-point of this process is that most bills will barely pass, unless they&#x27;re so hot politically that it&#x27;s easy to attack someone over messing with it (think some of the post-9&#x2F;11 terrorism related votes).
