The full sentence uttered by Mr. Obama on February 6, 2012 was: "Our Founders designed a system that makes it more difficult for me to bring about change than I would like sometimes."
Perhaps the reason the Founders designed such a system was that they were dealing with a King.
Note Jefferson's indictment in the second paragraph: "The History of the present King of Great-Britain is a history of repeated Injuries and Usurpations, all having in direct Object the Establishment of any absolute Tyranny over these States." This statement is followed by a bill of particulars consisting of some thirty specific accusations.
Now note these provisions of the Constitution of the United States of America:
All legislative power in Congress (Article I), including the power "To declare War" (Article I), and all judicial power in federal courts (Article III)--not in the President.
Congress (Article I) and a Supreme Court decision) can suspend habeas corpus--not the President.
Presidential oath: I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States. (Article II, Section 2).
The power of impeachment/conviction/removal resting in Congress is, at least in theory, a constraint on the President. Ask the first President Johnson, who survived by a hair. And, for that matter, President Nixon, who cut and ran before the House (pun intended) fell in on him.
Treaties with the "Advice and Consent of the Senate," if the President can muster a two-thirds vote of the Senators present. Ditto with major federal officials, including judges, with a majority vote.
And the grandaddy of them all: "The Congress, whenever two thirds of both Houses shall deem it necessary, shall propose Amendments to this Constitution, or, on the Application of of the Legislatures of two thirds of the several States, shall call a convention for proposing Amendments, which, in either Case, shall be valid for all Intents and Purposes, as Part of this Constitution, when ratified by the legislatures of three fourths of the several States, or by Conventions in three fourths thereof, as the one or the other Mode of Ratification may be proposed by the Congress."
(Article V of the Constitution of the United States of America.)
Yet Obama appoints Sotomayor and Kagan to the Supreme Court so that they can amend the Constitution without a nod to Article V.
"More difficult," indeed.
Apparently not so difficult as to prevent him from unfaithfully going to war in Libya.
Not so difficult as to prevent him from unfaithfully appointing "czars," and thus circumventing the "advise and consent" function of the Senate.
Not so difficult so as to prevent him from unfaithfully making recess appointments when there was no Senate recess.
Not so difficult so as to prevent him from unfaithfully instigating and then approving the largely unconstitutional Obamacare.
No, unfortunately, despite his whining protestation about how the Founders have constrained his good intentions, in fact much of what Obama has done has been "not so difficult."
It is frightening to think what else may be "not so difficult" if the alleged former constitutional law professor swindles another term out of a majority of the gullible American people.
