FWIW in June of last year, Obama allied with Senate Republicans, beating his own party, to get TPP fast tracked, meaning that the vote will be all or nothing, up or down, and will receive little debate, oversight, and no amendments before the vote.
The vote was 60-38.
Around that time, Clinton did refer to the secretly-written TPP as the "gold standard" in trade negotiations, but possibly due to pressure from Sanders and the rest of the party, has backed down, saying it was flawed and she doesn't support it.
Trump has also gone after the TPP numerous times, basically shoving a long-standing Republican establishment plank in their faces.
So weirdly both candidates oppose the TPP. I'm wondering if this is going to be saved for after the election, then jammed through.
