The greatness of our gedolei Yisroel is in their Torah, not their politics. I don’t ask an accountant for medical advice, and I don’t ask my rebbe how to vote. Besides, in our American system, people make up their own minds about how they will vote – they don’t wait for someone to tell them how to vote. In other countries, people vote the way they’re told to vote. Perhaps you’d rather live in one of those countries.
