Are any prominent Democrats other than Bob Menendez defending Bob Menendez?
By 
BUT MUH DUDE PROCESS!
Good question, with a good answer:
Serious question: Has any prominent Democrat lined up behind Robert Menendez in the same unabashed way that Republicans formed ranks around Clarence Thomas?— Ian Millhiser (@imillhiser) September 22, 2023
Notice how liberals' response to Bob Menendez is "so he finally got got" and not "this is a deep state plot from groomers and Jews, I am a gold expert and I can see those are fake."— Not up for trouble, please stop asking (@agraybee) September 22, 2023
I may be missing something, but I haven’t seen any Democrats claim that the indictment is some kind of Deep State conspiracy. I haven’t seen anyone pick out individual elements of the indictment and claim that innocuous behavior is being punished, except satirically:

I haven’t even seen specious claims that “due process” applies to individuals making inferences about the likelihood of someone’s guilt as opposed to the standard the state must meet before forcibly taking away someone’s liberty.* And needless to say Biden is neither going to attack the DOJ for indicting Menendez nor pardon him if he is convicted, a noted contrast to the person about to win the Republican nomination by near-acclimation. And the only person I’ve seen “play the race card” is Menendez himself:
“It is not lost on me how quickly some are rushing to judge a Latino and push him out of his seat. I am not going anywhere.” – Sen. Bob Menendez, responding to calls for him to resign from Congress. https://t.co/2ZEnBPdzRr— darlene superville (@dsupervilleap) September 22, 2023
Relatedly, it is perfectly fine to describe Menendez’s behavior as hopelessly corrupt and urge him to resign even if the Supreme Court continues to self-servingly make successful corruption prosecutions essentially impossible. Similarly, it is fine to say that it is deeply corrupt for a Supreme Court justice to accept millions and millions of dollars from wealthy ideologues with strong interests in the outcome of Supreme Court cases irrespective of whether any legal sanctions are ever applied, or to conclude that it is reprehensible and immoral for a powerful 40-year-old celebrity to have a sexual relationship with a 16-year-old schoolgirl and conclude that you do not wish to platform or associate with such a person even if this conduct is not illegal in the particular jurisdiction in which it occurred.
*Alas, Chuck Schumer appears to have taken this particular route — not conspiracy theorizing or attacks on the DOJ, and as part of an agreement to get him to step down from his committee, but still not ideal. New Jersey Dems have been much better:
~9 hours from "senior Democratic senator was indicted" to "the state's Democratic governor and Democratic heads of both houses of the state legislature call for him to step down." https://t.co/1JALwtHqdX— Matthew Gertz (@MattGertz) September 22, 2023
