Obama momentum

Edwards endorsement pays off for Obama

WASHINGTON - Barack Obama collected the support of four of John Edwards' Democratic National Convention delegates on Thursday, then gained the backing of a West Coast congressman and a large labor union as he marched steadily toward the party's presidential nomination.

The fresh support brought Obama's overall delegate total to 1,892, compared to 1,718 for his rival, Hillary Rodham Clinton. It takes 2,026 to clinch the nomination at the party convention in Denver this summer.
