Edwards ends bid for democratic presidential nomination

John Edwards has officially announced that he's ending his presidential campaign.

Addressing supporters in Raleigh, North Carolina, Edwards spoke highly of John Kerry, who soundly defeated him in Tuesday's Super Tuesday primaries.

Edwards says Kerry is fighting for the causes that Edwards' own supporters embrace -- including more jobs, better health care, and a cleaner environment. He says Kerry is showing the same strength, resilience and courage that he showed when he was fighting for his country in Vietnam.

Edwards vowed to do everything in his power to make Kerry the next president of the United States -- and he asked his supporters to do the same.

Advisers to Edwards have made it clear he wouldn't reject an invitation to be Kerry's running mate.
