In context of my prior post in reply to yours, considering race... this should help clarify much of the confusion that exists in the shifting lines in politics, today... that is about topics other than race:  
  This is taken from "A collection of the political writings of William Leggett" openlibrary.org
  Leggett was a newspaper editor... a Democrat... (and not an abolitionist) here writing on the exact subject of the differences between the parties (ignoring the issues of race and slavery) as he saw it... in 1834:
  THE DIVISION OF PARTIES. 
  [From the Evening Post, November 4, 1834.]  Since the organization of the Government of the  United States the people of this country have been divi  ded into two great parties. One of these parties has un  dergone various changes of name ; the other has con  tinued steadfast alike to its appellation and to its princi  ples, and is now, as it was at first, the DEMOCRACY.  Both parties have ever contended for the same opposite  ends which originally caused the division whatever  may have been, at different times, the particular means  which furnished the immediate subject of dispute. The  great object of the struggles of the Democracy has been  to confine the action of the General Government within  the limits marked out in the Constitution : the great ob  ject of the party opposed to the Democracy has ever been  to overleap those boundaries, and give to the General  Government greater powers and a wider field for their  exercise. The doctrine of the one party is that all pow  er not expressly and clearly delegated to the General  Government, remains with the States and with the Peo  ple : the doctrine of the other party is that the vigour  and efficacy of the General Government should be  strengthened by a free construction of its powers. The  one party sees danger from the encroachments of the  General Government ; the other affects to see danger  from the encroachments of the States. 
  This original line of separation between the two  great political parties of the republic, though it existed  under the old Confederation, and was distinctly marked  in the controversy which preceded the formation and  adoption of the present Constitution, was greatly widen  ed and strengthened by the project of a National Bank,  brought forward in 1791. This was the first great ques  tion which occurred under the new Constitution to test  whether the provisions of that instrument were to be in  terpreted according to their strict and literal meaning ;  or whether they might be stretched to include objects  and powers which had never been delegated to the Gen  eral Government, and which consequently still resided  with the states as separate sovereignties. 
  The proposition of the Bank was recommended by the  Secretary of the Treasury on the ground that such an in  stitution would be " of primary importance to the prosper  ous administration of the finances, and of the greatest  utility in the operations connected with the support of pub  lic credit." This scheme, then, as now, was opposed on  various grounds ; but the constitutional objection consti  tuted then, as it does at the present day, the main reason of  the uncompromising and invincible hostility of the de  mocracy to the measure. They considered it as the ex  ercise of a very important power which had never been  given by the states or the people to the General Govern  ment, and which the General Government could not  therefore exercise without being guilty of usurpation.  Those who contended that the Government possessed the  power, effected their immediate object ; but the contro-  versy still exists. And it is of no consequence to tell  the democracy that it is now established by various pre  cedents, and by decisions of the Supreme Court, that  this power is fairly incidental to certain other powers  expressly granted ; for this is only telling them that the  advocates of free construction have, at times, had the  ascendancy in the Executive and Legislative, and, at all  times, in the Judiciary department of the Government.  The Bank question stands now on precisely the same  footing that it originally did ; it is now, as it was at first,  a matter of controversy between the two great parties of  this country between parties as opposite as day and  night ^-between parties which contend, one for the conso  lidation and enlargement of the powers of the General  Government, and the other for strictly limiting that  Government to the objects for which it was instituted,  and to the exercise of the means with which it was en  trusted. The one party is for a popular Government ;  the other for an aristocracy. The one party is compos  ed, in a great measure, of the farmers, mechanics,  labourers, and other producers of the middling and low  er classes, (according to the common gradation by the  scale of wealth,) and the other of the consumers, the rich,  the proud, the privileged of those who, if our Government  were converted into an aristocracy, would become our  dukes, lords, marquises and baronets. The question is  still disputed between these two parties it is ever a new  question and whether the democracy or the aristocracy  shall succeed in the present struggle, the fight will be re  newed, whenever the defeated party shall be again able to  muster strength enough to take the field. The privilege  of self-government is one which the people will never be  permitted to enjoy unmolested. Power and wealth are  continually stealing from the many to the few. There  is a class continually gaining ground in the community,  who desire to monopolize the advantages of the Govern-  ment, to hedge themselves round with exclusive privileges,  and elevate themselves at the expense of the great body  of the people. These, in our society, are emphatically  the aristocracy ; and these, with all such as their means  of persuasion, or corruption, or intimidation, can move to  act with them, constitute the party which are now strug-  ling against the democracy, for the perpetuation of an  odious and dangerous moneyed institution. 
  Putting out of view, for the present, all other objections  to the United States Bank, that it is a monopoly, that  it possesses enormous and overshadowing power, that it  has been most corruptly managed, and that it is identified  with political leaders to whom the people of the United  States must ever be strongly opposed the constitutional  objection alone is an insurmountable objection to it. 
  The Government of the United States is a limited  sovereignty. The powers which it may exercise are ex-  pressly enumerated in the Constitution. None not thus  stated, or that are not " necessary and proper" to carry  those which are stated into effect, can be allowed to be ex  ercised by it. The power to establish a bank is not ex-  pressly given ; neither is incidental ; since it cannot be  shown to be " necessary" to carry the powers which  are given, or any of them, into effect. That power can-  not therefore be exercised without transcending the Con-  stitutional limits. 
  This is the democratic argument stated in its briefest  form. The aristocratic argument in favour of the  power is founded on the dangerous heresy that the Con-  stitution says one thing, and means another. That ne  cessary does not mean necessary, but simply convenient.  By a mode of reasoning not looser than this it would be  easy to prove that our Government ought to be changed  into a Monarchy, Henry Clay crowned King, and the op-  position members of the Senate made peers of the realm ;  and power, place and perquisites given to them and  their heirs forever.  |
