The end of this divisiveness will  never emerge from the corrupted sewer created by the two party system which offers more hate than hope.  This danger was foreseen by John Adams, 2nd President of the United States:  

 "There is nothing which I dread so much as a division of the republic into two great parties, each arranged under its leader, and concerting measures in opposition to each other. This, in my humble apprehension, is to be dreaded as the greatest political evil under our Constitution."

-- John Adams, Letter to Jonathan Jackson (2 October 1780), "The Works of John Adams", vol 9, p.511
