SEN. TED KENNEDY (D-MA): “You Have Obviously Had A Very Distinguished Record, And I Certainly Commend You For Long Service In The Public Interest. I Think It Is A Very Commendable Career And I Am Sure You Will Have A Successful One As A Judge.” (Sen. Ted Kennedy, Committee On The Judiciary, U.S. Senate, Hearing, 4/5/90)
SEN. FRANK LAUTENBERG (D-NJ): “I Believe Mr. Alito Has The Experience And The Skills To Be The Kind Of Judge The Public Deserves – One Who Is Impartial, Thoughtful, And Fair. I Urge The Senate To Confirm His Nomination.” (Sen. Frank Lautenberg, Congressional Record, 4/27/90, p. S5281)
FORMER SEN. BILL BRADLEY (D-NJ): “[T]he Confirmation Of Sam Alito As U.S. Attorney For New Jersey Is Testimony To The Commitment He Has Shown And The Success Of His Efforts As A Law Enforcement Official. I Am Confident That He Will Continue To Do All He Can To Uphold The Laws Of This Nation With The Kind Of Determination And Vigor That Has Been His Trademark In The Past.” (Sen. Bill Bradley, Congressional Record, 12/8/87, p. S17427)
There's more out there. It's also worth mentioning that Alito was unanimously confirmed to the federal court of appeals by the Senate back in 1990.
I expect that some of these people will be changing their tune shortly.
