LONGFELLOW in 'A Psalm of Life' wrote: Not enjoyment, and not sorrow, Is our destined end or way;But to act, that each to-morrow Brings us farther than to-day. By such an image a Progressive is someone who moves us all forward, working in earnest to do the best in what they do. And, knowing that what gets us farther along requires positive relationships a Progressive instinctually does the good, the just and the fair for all parties, so that no one is deprived by their action and the least among us is included and benefitted. Finally, a progresive is an active participant in shaping the future and not just a spectator in the body politic.
