"Complaints are every where heard from our most considerate and virtuous citizens, equally the friends of public and private faith, and of public and personal liberty; that our governments are too unstable; that the public good is disregarded in the conflicts of rival parties; and that measures are too often decided, not according to the rules of justice, and the rights of the minor party; but by the superior force of an interested and over-bearing majority. However anxiously we may wish that these complaints had no foundation, the evidence of known facts will not permit us to deny that they are in some degree true."
-James Madison, The Federalist No. 10
