If Sanders and Warren were telling the truth, they'd argue FOR, not against, the TPA.

126. the 'switches' are cosmetic bull

...designed to make it appear that Congress will be able to shut the bill down if they disapprove of the language.

What the president well knows is that this particular Congress, this republican dominated Congress, will not reject the trade pact and has a sufficient number of Democrats already on board with the deal to reject any attempt to 'switch' off the TPA. It's a cynical and insincere agreement for the TPA which does virtually nothing to change the fast track framework where Congress will be voting, up or down on an already signed treaty.

That makes your argument that Warren and Sanders are lying untrue. Once the TPA, as agreed to, is passed, there's nothing really standing in the way of the signed TPP's passage in this Congress; just a slow-motion theater which is designed to make it appear there's some actual input from Congress on this corporate-derived and crafted trade pact.
