I called my senator, Ron Wyden, who also happens to be head of the Senate Finance Committee to express my concerns on TPP, which are the same as the concerns of many on this site. The following is paraphrasing what his spokesperson told me.
The senator does have concerns about this bill, particularly the lack of transparency of the process. He won't take a stand on whether he supports it or not, because he hasn't read it. However, he is not in favor of fast-track authorization.
Hard to see fast-track authorization being approved with the Senate Majority Leader and the Finance Chairman opposing it. Now if we lose the senate in 2014, things could change. A good reason for the Republicans to go all out to win the senate in 2014, even if they are almost sure to lose it in 2016 and a good reason for us to keep them from doing so, even if that means supporting some Dem senators we are less than enthusiastic about.
