Liberal TPP opponents this month have launched a new wave of petition campaigns and fundraising drives; a free concert series is touring the country through the summer; and lawmakers on Capitol Hill are vowing to do "everything we possibly can," in the words of Rep. Rosa DeLauro (D-Conn.), to block a vote this year. Obama on Friday sent notice to Congress that he intends to deliver TPP implementing legislation to Capitol Hill later in the year — a maneuver dictated by the fast-track trade resolution Congress passed in 2015. Obama's move is a clear indication that the president, far from bowing to liberal pressure, will instead push full-throttle to try to pass the enormous 12-nation agreement — the largest in U.S. history — before he leaves office.
