Biden nominated to be VP candidate

Sen. Joe Biden was nominated by Democratic convention delegates Wednesday to take the second spot on the party's 2008 presidential ticket with trailblazing Sen. Barack Obama. Biden was nominated by acclamation by the delegates not long after Obama, the Illinois senator, had his place in history secured, also by unanimous convention vote. Biden said in an acceptance speech that the challenges America faces require "more than a good soldier" in the White House. And he called Obama a wise leader who can deliver the change the nation needs.
