Updated: Two State Senators from Middlesex County, Robert Smith and Barbara Buono, have endorsed Rob Andrews for the Democratic U.S. Senate nomination.  A third Senator, Joseph Vitale, is expected to join them.

"We have the privilege of representing the people of Middlesex County and know their concerns well.  We respect the service of Senator Frank Lautenberg in all respects.  After consulting with our communities and carefully considering the options, we have concluded that New Jersey and the country need new leadership and thus we will support your campaign for the United States Senate," Smith and Buono wrote in a letter to Andrews.

"While effectively serving your congressional district, you have always remained dedicated to all New Jersey residents, especially when it comes to issues such as education, healthcare, the environment and the interests of our seniors.  Your unique knowledge of such a broad range of issues facing New Jersey and the country is truly invaluable, which makes you a great candidate to serve the entire state of New Jersey,"  the Senator said.  "Your record as a legislator and your unwavering commitment to the residents of New Jersey over the past 18 years has earned you the respect of residents throughout the state.  We believe it is time to give the voters of New Jersey a choice in this year's primary, and thus we want to make public our endorsement for your candidacy to seek the Democratic nomination for United States Senate.  We are proud to stand with you in a positive, substantive campaign to change New Jerse  and the nation for the better."
