It agitates the Community with ill founded Jealousies and false alarms, kindles the animosity of one part against another, foments occasionally riot & insurrection.
Also from Washington’s farewell address (who was strongly against political parties as we have them today:
All obstructions to the execution of the Laws, all combinations and associations, under whatever plausible character, with the real design to direct, control, counteract, or awe the regular deliberation and action of the constituted authorities, are destructive of this fundamental principle, and of fatal tendency. They serve to organize faction, to give it an artificial and extraordinary force; to put, in the place of the delegated will of the nation, the will of a party, often a small but artful and enterprising minority of the community; and, according to the alternate triumphs of different parties, to make the public administration the mirror of the ill-concerted and incongruous projects of faction, rather than the organ of consistent and wholesome plans digested by common counsels, and modified by mutual interests
Many proposals that go through the House today look at nothing other than those narrow interests of budgeting and faction promotion, without looking at “mutual interests”.
Then again, block voting only works to further the interests of the minority over mutual interests.
