( L - R ) Obama, Clinton

WASHINGTON (AP):

Democrat Hillary Rodham Clinton faced some of the harshest criticism yet from Barack Obama, her rival for the party's presidential nomination, who accused her of having no restraint and using tactics typical of Republicans.

The New York senator, who trails Obama by 10 percentage points nationally in the latest Gallup Poll tracking survey, meanwhile sought to cement working-class votes in the looming Pennsylvania primary by saying Monday that her husband was wrong to push through a free trade deal with Canada and Mexico. She vowed to change or walk away from the pact that many Americans hold responsible for a loss of United States jobs.

Obama made his comments at an Associated Press annual meeting following a question about whether the long nomination battle was hurting the Democratic party's chances at the White House.
