The House voted to resurrect the centerpiece of President Obama’s trade agenda Thursday, six days after his fellow Democrats dealt him a dramatic setback after a months-long lobbying effort.

Thursday’s 218-to-208 vote to grant Obama “fast track” authority to negotiate trade deals — including the controversial 12-nation Trans-Pacific Partnership — is a win for the president, but it is not yet a victory.

It is the first in a complicated series of moves to get around a blockade set up by liberal House Democrats against the president’s trade agenda.
