Ferris WhartonRepublican Ferris Wharton says he has decided against a second run for Delaware attorney general.
Wharton, a former chief deputy attorney general who is now a public defender, lost the 2006 race to Democrat Beau Biden but took more than 47% of the vote.
Wharton said Thursday that he has ruled out a second campaign against Biden, saying he likely could not match the son of the vice president in fundraising.
Biden is recovering at a Philadelphia hospital where he was taken Tuesday after suffering a mild stroke.
