Representatives voting against your interest – and theirs

The following is a letter to the editor that didn’t get published because it’s “too long.”:

We have a smart and (ha-ha) funny Congressman in Derek Kilmer.  He grew up in Port Angeles and it feels like he really cares about this area: trying to balance the economic and environmental interests in our community.  But there’s something missing.  Kilmer is in favor of the Trans Pacific Partnership (TPP), a kind of NAFTA-on-steroids bill.  It’s somewhat unclear what the TPP would do, because it’s been written behind closed doors by corporations, and is allowed only an up-or down vote in Congress.
However, we do know some things about the TPP.  It would ship jobs overseas (if there are any left to send).  It would let corporations sue our government in arbitration courts (where the corporation is always correct)   According to “The Trans-Pacific Partnership clause everyone should oppose” (Washington Post, Feb. 25, 2015) the same lawyers who represent a corporation can be a judge on the next corporation v. government case.
Also according to the Washington Post, this has already happened.  Recently.  See “TransCanada is suing the U.S. over Obama’s rejection of the Keystone XL pipeline. The U.S. might lose.” (Jan, 8, 2016).  A suit for $15,000,000,000 (15 billion dollars).
Patty Murray and Derek Kilmer are both in favor of giving Obama “fast-track” authority to negotiate the TPP, which goes around the point of Congress.  Both of them, along with Larsen DelBene, were denied an endorsement by the Washington State Labor Council
It’s not only about the Trans Pacific Partnership.  Murray and Kilmer are both up for election  this  year, and both committed their super-delegate vote to Clinton before any other contestants entered the race, and have never reconsidered, despite the fact that Washington went for Sanders 73% to Clinton’s 27%, in the caucuses where delegates are assigned.  They have also disregarded the fact that Sanders does better in the polls (beats Trump by 10-15%) than Clinton does (see Real Clear Politics).
There has been little news published about challengers to Murray or Kilmer.  Phil Cornell is a Democrat running against Murray.  He is against the TPP, in favor of single-payer healthcare, and against the super delegate system.
Derek Kilmer has three challengers; perhaps because he didn’t take a stand on TPP, or remained an unpledged super delegate.  According to Tyler Vega’s website (he prefers the Green Party, and is running against Kilmer), Vega has suspended his campaign, and has joined Paul Nuchim (preference: Democrat) in endorsing the other progressive challenger to Kilmer: Mike Coverdale (prefer: Independent).  In an unusual year, candidates are coordinating to break the hold on our two-party system.
Mike Coverdale calls for overturning Citizens United, is against the TPP, and wants to get money out of politics.
So, who will you vote for?  The incumbents who won’t commit to representing and protecting the people, or the challengers who will represent the people of Washington, and the North Olympic Peninsula?
