In August, Governor-elect Jon Corzine contributed $2,600 to Albio Sires’ campaign for Congress — a campaign that only takes place if Corzine appoints Bob Menendez to the United States Senate. Corzine gave Sires $500 on August 7th and then another $2,100 eleven days later. Sires has already raised $250,818 — more than three times the total amount her raised the last time he ran for Congress: 1986, when he was the Republican nominee against incumbent Frank Guarini.
