Democrats were encouraging Kerrey, 64, to join the race to replace Sen. Chuck Hagel, R-Neb., who announced last month wouldn't seek re-election, WOWT-TV, Omaha, Neb., said Wednesday.
Kerrey cited family and his work as president of New School University in New York in his decision not to run.
WOWT-TV said Democrats will likely turn to Omaha Mayor Mike Fahey as their next choice.
