Joe Biden has won a seventh term in the Senate, defeating Republican challenger Christine O'Donnell. The call is based on an analysis of voter interviews, conducted for The Associated Press by Edison Media Research and Mitofsky International.

Biden won't serve a full Senate term if running mate Barack Obama wins the presidency.

Under that scenario, Biden resigns his Senate seat and Delaware gets a new Democratic senator. Outgoing Democratic Gov. Ruth Ann Minner would likely appoint Biden's replacement. Potential contenders include Lt. Gov. John Carney and the senator's son, Attorney General Beau Biden.
