WASHINGTON – The House narrowly approved the Central American Free Trade Agreement early Thursday, a personal triumph for President Bush, who campaigned aggressively for the accord he said would foster prosperity and democracy in the hemisphere.

The 217-215 vote just after midnight adds six Latin American countries to the growing lists of nations with free trade agreements with the United States.

The vote, supposed to take 15 minutes, dragged on for an hour as negotiations swirled around the floor among GOP leaders and rank-and-file members reluctant to vote for the agreement. In the end, 27 Republicans voted against CAFTA, while 15 Democrats supported it.

Democrats Tom Allen and Mike Michaud of Maine voted against the measure.

Supporters had to overcome what some have called free trade fatigue, a growing sentiment that free trade deals such as the North American Free Trade Agreement with Mexico and Canada have contributed to a loss of well-paying American jobs and the soaring trade deficit.
