The 17th did more damage to America than any other amendment, including the 16th.
However, I believe the reality is that, the repeal of any amendment to the constitution is beyond the reach of any single president (let alone in less than 2 years). So I find Lazamataz's conditionals on voting for GW, in the event he were to sign a CFR bill, to be unrealistic and again your position is predisposed without consideration of what the Courts or other future events may bring.
