Gov Pat Quinn has called for the party to band together and work as a ticket despite recent clashes among top Democrats.
His comments came Sunday during the state Democratic party's meeting to slate statewide candidates for the 2014 primary.
The 23 state central committeemen unanimously voted to give the party's official endorsement. Five of six candidates are unopposed in the Democratic primary.
Another 15 committeemen who did not make the trip to Springfield gave Democratic Party Chair Michael Madigan power to vote in their absence.
Attendees included U.S. Sen. Dick Durbin, Quinn and Lt. Gov. Sheila Simon, who's running for comptroller.
The meeting was set before former White House chief of staff Bill Daley dropped out of the gubernatorial race, predicting Quinn would lose.
He was Quinn's top challenger.
