It seems unlikely that anybody would be able to negotiate any changes within the system that the WTO wouldn't overrule as a "barrier to free trade". So you have to get our trading partners to agree, the WTO to agree, and even then, you'll still be facing multimillion dollar lawsuits from corporations which they have the right to file under Article 11 of NAFTA. The only way around that is to either try & reform that law (with corporate agreement) or toss out NAFTA altogether. Now tell me which plan is the real "fast track" - Edwards' or Kucinich's?
here's an article that explains the self-licking ice-cream cone that the corporatists have created for themselves:

Organized secretively by national leaders and representatives of multinational corporations from all over the globe, NAFTA, WTO and now FTAA take decision-making power out of the hands of states or local communities and transfer it to faceless bureaucracies controlled by unelected corporate representatives. Under these transnational institutions, anything construed as a barrier to "free trade" can be challenged and repealed.
Thus a foreign business can file a protest against state, county or city standards that protect food safety or public health, establish safeguards for working people on the job, or establish anti-pollution regulations, claiming that such measures are "unfair" trade practices. Then a NAFTA, WTO or FTAA tribunal -- consisting of corporate lawyers and meeting without public input -- can overturn those regulations, local wishes notwithstanding. Such anti-democratic practices may only get worse if fast track and FTAA are approved.
Fast track would allow the president's team to negotiate with other nations without any public input, and then would limit debate on and amendments to any agreement, and finally force a straight up or down vote on the FTAA bill. Citizens and even senators would have a limited role in such an important piece of legislation, a situation that raises constitutional questions as well as serious concerns about our democracy.
If enacted, the FTAA will centralize even more the power of corporations and the state to act as they wish without a voice from local communities, citizens or courts. Indeed, this is already happening. Foreign firms have brought challenges to U.S. laws and legal decisions under Chapter 11 of NAFTA, which established a broad definition of investment and property rights, and allows them to sue for damages when U.S. standards restrain their ability to trade.
