Supporters of the Trans-Pacific Partnership (TPP) are likely to put up a huge fight in an effort to pass the 12-nation Pacific Rim agreement during the closing days of the congressional session. Why? Because they realize that with two anti-TPP nominees at the top of both major party tickets, it is likely their best chance to get this deal done.

Congress canít let this happen. A growing bipartisan coalition of lawmakers opposes the agreement, including recent converts vice presidential nominee and Sen. Tim Kaine (D-Va.) as well as House Minority Leader Nancy Pelosi (D-Calif.). Thatís an encouraging sign. But victory is far from a given.

In an age when corporate influence in public policy is on the rise, the TPP represents the next level. The proposed pact includes 40 percent of the global economy and represents a huge opportunity for big business to grow its profits even more. Never mind concerns over corporate greed, lost jobs, the environment or unsafe food or products Ė those are inconsequential for CEOs looking to bolster their bottom lines.
