It would be even better if bochurim have educated opinions about who and what they are voting for.
Rav Moshe wrote that voting is showing hakaras hatov. What exactly did he mean? I presume not only that non-Jews check that Jewish towns voted (that would be Hillul Hashem issue) and not simply to “fund our yeshivos” (that would be “self interest”) but actually knowing what is good for the country and voting accordingly.
