Historically, when sweeping policy changes or legislation of indelible consequence are signed into law, Presidents receive the credit. There is a good reason for that. Without the Chief Executive putting his pen to paper, these advancements would have nary a chance of becoming reality. In most cases, though, a President's signature is simply the culmination of a long fight to make an idea or actual proposal a reality. In fact, quite often it is members of Congress who nurture proposals from inception to the President's desk. Like a train leaving its first station, the legislative process often starts with a handful of people on board until slowly, a few more passengers hop on at each stop and before long, there is a full car with people standing in the aisles. Often times, a bill becoming a law is no different.
