Drop TPPBased on Trump's own statements, the United States isn't likely to be involved in TPP any time in the near future, if ever. This is not a popular concept in Republican ranks, nor for most who consider themselves somewhere right of left and left of right. There's a good chance that TPP is effectively dead, at least for the remainder of Trump's presidency.
TPP is dead. Trump signed it's death certificate today via Executive Order. Trade agreements are free to be negotiated individually, rather than as a group. A campaign promise completed.
