Ruth Conniff, Common Dreams:

For years, both major parties pushed multinational corporations’ agenda in big trade deals. But not this year. Growing public ire over NAFTA, especially in the Rust Belt, which has seen more than 57,000 factories offshored, has changed the political debate. St. Louis points out: 

“Now the candidates are fighting over who hates the TPP more. That is a prudent response since all of the trade unions, environmental groups, LGBT organizations, women, retirees—the entire progressive base is opposing TPP.

It’s not about trade or not trade, it’s about who writes the rules and who benefits."

Overall, the trouble with the TPP is that it “doesn’t learn the lessons of NAFTA,” St. Louis says. “It expands incentives for offshoring and creates more opportunities to challenge environmental and health and safety laws through secret tribunals.”
