Biden tours Ford-Mazda plant in southeastern Mich.

FLAT ROCK, Mich. (AP) - Joe Biden has toured an auto assembly plant in southeastern Michigan, shaking hands with blue-collar workers and managers and telling them the auto industry is crucial to America's economic future.

The Democratic vice presidential candidate toured the joint Mazda-Ford plant in Flat Rock on Monday. He stopped to rev the engine of a bright red Ford Shelby convertible to a round of applause from watching workers.

Biden says the management and rank-and-file work force of the auto industry is what built the American middle class.

He spoke before an evening campaign rally in Flat Rock. Earlier in the day, he spoke at a rally at St. Clair Shores high school.
