John Sutherland:"The Constitution was developed by 18th century elites allegedly for the states, and by adding the two additional branches of government to the confederation of states (i.e. the executive branch and the judicial branch) sealed our fate. In my opinion. Bill Buppert seems to agree.

"The Constitution is an enabling document for big government. Much like the Wizard of Oz, the man behind the curtain is a fraud. In this case, for all the sanctimonious hand-wringing and the obsequious idolatry of the parchment, it sealed the fate of our liberties and freedoms and has operated for more than 200 years as a cover for massive expansion of the tools and infrastructure of statist expansion and oppression." -- Bill Buppert
The U.S. Constitution has only 27 amendments, the last of which (a limit on Congressional pay increases) was ratified in 1992. 
In August 2013, nearly four years after this proposed 28th amendment began making the rounds on the Internet, two Congressmen (Ron DeSantis of Florida and Matt Salmon of Arizona) did introduce a joint resolution (H.J.RES.55) similar to one of its elements, proposing an amendment to the Constitution stating that “Congress shall make no law respecting the citizens of the United States that does not also apply to the Senators and Representatives.” That bill died in committee.
​
The idea of a 28th Amendment to the U.S. Constitution may indeed be one "whose time has come," and there's some historical truth to the claim that Congress has sometimes exempted itself from laws that apply to the rest of us.

Could this amendment be passed without Congress voting on it?
Yes and no. Article 5 of the U.S. Constitution specifies two procedures for amendments. One method is for two-thirds of states legislatures to call for a constitutional convention at which new amendments may be proposed, subject to ratification by three-fourths of the states.

The constitutional convention method allows for the Constitution to be amended by the actions of states alone and cuts Congress out of the equation — no Congressional vote or approval is required. However, not once in the history of the United States have the states ever called a convention for the purpose of proposing new constitutional amendments. It only takes 34 (of the 50) States to convene a Constitutional Convention.

The other method for amending the Constitution (the one employed with every amendment so far proposed or enacted) requires that the proposed amendment be approved by both houses of Congress (i.e., the Senate and the House of Representatives) by a two-thirds majority in each, and then ratified by three-fourths of the states. It’s probably safe to speculate that the odds that a super majority of both houses of Congress would pass an amendment which placed such restrictions upon them are very low indeed.

"Be it reaffirmed that this Constitution for the United States, including the Bill of Rights, shall be the ruling law of the land, and no federal legislation shall be enacted in contradistinction to the Founder’s intent of this Constitution. With the passage of this 28th amendment to the Constitution, all existing amendments from Amendment 11 through Amendment 27 are hereby repealed and rescinded.
