While these types of movements have difficulty being effective (i.e. producing a popular movement that results in ratification) the 28th amendment proposal is nevertheless a movement that I became a supporter of from my first reading of their proposal. This is cleverly crafted, as it summarizes the majority of changes needed to restore the integrity of the Constitution and turn the tide of the current tyrannous bloat known as the Federal Government.

The 28th Amendment to the Constitution of the United States of America

First Draft Proposal

Section 1.

The 16th Amendment to the Constitution of the United States is hereby repealed.

Section 2.

Congress may collect no revenue by any means other than a flat individual income tax not to exceed 15% of an individual's earnings, a flat corporate tax not to exceed 10% of net revenues, and actual user fees for services. All citizens and businesses shall be taxed at the same rate, and no exceptions, exemptions or credits will be allowed.

Section 3.

A. Any budget passed by the Congress must be funded by actual revenues collected through taxes as described in Section 2. Except in time of War as defined below, no deficit spending, borrowing on future funds, borrowing from other entities or other mechanism to meet budget requirements will be allowed.

B. For purposes of this section, "War" shall be defined as hostilities declared by the President of the United States in his Constitutional role as Commander-in-Chief, and duly authorized by the Congress under the terms of the "War Powers Act" of 1973. Any funds borrowed shall be used exclusively for executing that War and shall be re-paid entirely no later than 15 years from the end of the War.

Section 4.

All agencies, programs, entitlements and other devices that will be excised by budgetary requirements will be returned to the responsibility of the individual States. No federal regulations or legislation will dictate how the States fund or execute such devices.

Section 5.

The Congress may not make State eligibility for redistribution of revenue contingent on compliance with regulations or legislation that has the effect of a nationally uniform standard.

Section 6.

Those areas of federal responsibility prescribed by the original Constitution will have budgetary priority. No bill will be passed that funds any other concern without first meeting the budgetary requirements of these areas. No funding will be included in the budget for a concern that is the responsibility of and reserved to the States.

Section 7.

Article I, Section 8, Clause 3 of the United States Constitution is hereby amended to read as follows:

"To regulate commerce with foreign nations and with the Indian tribes"

Section 7 was the only part that I didn't understand, but the site explains that it removes the "interstate commerce" clause which the Federal Government has often cited as the constitutional backing for its creeping scope.

 UPDATE: I've signed up to receive updates from the website... Two points I wanted to raise as a result of those updates: First, the above version is actually the second draft, incorrectly marked at the time I copied and pasted from their site.

Second, they are looking for volunteers for this group, so if you see the value in this amendment proposal, please sign up to receive their updates to keep informed, and tell others. They are also looking for volunteers for specific positions, so if you have the time and inclination, check them out!
