As much as I agree with the substance of what the rabbis say, I am very uncomfortable with injecting religion into politics.
(And I say this as someone who recently served on the Board of Directors of an Orthodox shul.)
No matter what the left of today will have you believe, religion has been "injected" into politics in the United States since the founding of the Republic. There are many ways in which this has played out over the years, and most of these have been non-threatening to religious freedom as a whole.
In this case, clergy advocating a mainstream political or legal position based on their religious principles is very much consistent with the historical tradition of American politics.
“I am very uncomfortable with injecting religion into politics.”
A common defense mechanism, bred into us in ghettos.
Keep your head down. Don’t bring attention to yourself.
And also why the JINOS are the face of Judaism in America.

The Seven Noachide Laws are objectively binding on the entire non-Jewish portion of the human race. Non-Jews are even required to set up courts of law to enforce them. The "separation of religion and politics" is a modern, un-Jewish concept. It's a good ideological justification for getting the goyim to let Jews live in peace, but unfortunately in the past two hundred years many Jews seem to have gotten the mistaken idea that it's actually part of Judaism rather than a purely utilitarian position.
About three hundred years ago all Jews lived as a self-governing Theocratic community under the civil authority of the rabbinate. With moslems spreading sharia around, perhaps Jews should give some thought to returning to that polity.
