Obama's Trans-Pacific Trade Plan Splits Democratic Base

President Obama has championed the TPP but it is not popular with trade unions that have historically been a powerful base of the Democratic Party.  Dana Milbank is a fairly moderate liberal reporter for the Washington Post.  He describes the problems that the trade deal poses for the 2016 election.  Republicans are united behind the TPP for variety of reasons.  Free trade is part of their catechism, and it certainly helps multinational corporations.  It should have been combined with programs that will help affected segments of the labor force adapt to a changing labor market, but that has not been done.
