* The United States Congress does not really get line-item veto on giant international trade agreements that affect dozens of countries, all of whom also must ratify the treaty.
* Trade promotion authority is simply the authorization for the administration to negotiate the treaty.
* By the time TPP is ratified by Congress at the end of 2016, it will have been public for over a year, and we'll have change-bars for the "legal scrub" stuff Techdirt is so worried about.
My real objection to US concern over TPP is that TPP has minimal impact on US domestic law. If you're a New Zealander, or, worse, Vietnamese, I totally understand how the TPP is problematic. The idea that a treaty that mostly serves to normalize global trade rules around the ones already in place in the US has been "rammed through in the USA" seems pretty arrogant to me.
