Back in '93/94 I read a book called, The Ruling Class: Inside The Imperial Congress, by Eric Felton of the Heritage Foundation. It outlined many problems with Congress at the time. One of the problems was how the Libs ran Congress as an "incumbent machine", first and foremost. Since the Pubs took over, they have been assimilated by this incumbent machine, apparently, overwhelmed by its influence.
I hope I am wrong in saying that the only way to limit the Fed gubmint is to choke the money supply via income tax, if that is ever possible. There was a group of people who were trying to establish, in a legit' way, the invalidity of the ratification of the 16th amendment. I have my doubts. However, if they can prove that, at least, four states did not genuinely ratify that amendment then there is a starting point to reverse the income tax/IRS/withholding/etc., yet only a starting point, IMHO.
