Yet there it was in black and white: "RIFT AMONG PROGRESSIVES EMERGES ON TPP," read a headline in Politico's daily labor and employment tipsheet, Morning Shift. The short item detailed the emergence of the "Progressive Coalition for American Jobs" -- a group of "progressives and Democrats committed to leveling the playing field for American workers," according to the coalition's barebones website. The website adds that "it's critical that we give the president trade promotion authority and establish the Trans-Pacific Partnership."

There's something weird about the group, though: No one in the Washington, D.C., progressive community seems to have ever heard of them before
