Precedent is a powerful thing. Once something has been established as acceptable behavior, there will inevitably be a flood of eager followers. That is why trailblazers get all the credit. The brave souls who test the waters, who first go where no one else dares, who push the envelope and set the stage for the rest of us. In many walks of life, such as science, exploration, and philosophy, these people are heroes, pushing mankind forward even when it is dangerous to do so. In politics, however, the trailblazer all too often covers territory that would have been better left unexplored.
