Edwards, Giuliani Throw in the Towel

"Elections are about a lot more than just candidates. Elections are about fighting for a cause larger than ourselves," Giuliani said.

In a statement from his campaign, Democratic rival Barack Obama said Edwards "spent a lifetime fighting to give voice to the voiceless and hope to the struggling, even when it wasn't popular to do or covered in the news."

"While his campaign may end today, the cause of their lives endures for all of us who still believe that we can achieve that dream of one America," the statement said." http://www.usatoday.com/news/politics/election2008/2008-01-30-campaign-wrap_N.htm
