This is a necessary and enlightened agreement to put a check on China that does not respect international rules, and give non-Chinese Asian allies and US an economic boost. Whoever is leaking this is not doing a service to the world as it only panders to a misguided populist impulse. This agreement is leading us towards a more free and prosperous world.
100% agreed on impulses of all sorts by citizens who don't understand what the TPP is about. But this is because there is no discussion about it on frank terms - the US can't even take a real stance on it and have to work in vaguaries and "and for national security". The closest they came was Obama's SotU. Without a real explanation there no way for citizens to understand, so they panic. And populists do have legitimate grievances.
