Bob Graham Ends Presidential Campaign Tuesday October 7, 2003 3:01 AM By NEDRA PICKLER Associated Press Writer WASHINGTON (AP) - Bob Graham, a political veteran whose low-key style failed to gain traction in the crowded Democratic presidential race, said Monday night he was ending his campaign. ``I'm leaving because I have made the judgment that I can not be elected president of the United States,'' Graham said in announcing his exit from the race on CNN's ``Larry King Live.'' He said he was not successful because he started his campaign too late and had trouble raising money.
