As a United States Senator,  Bernie Sanders’ job is to protect  his constituents in this life, and leave the questions of the existence, or lack therefor, and the nature of any afterlife to the theologians, or so you would think, video:

United States Constitution, Article VI, Section 3.:

… but no religious test shall ever be required as a qualification to any office or public trust under the United States.

If Senator Sanders believes in what he professes, to be Jewish, and his beliefs are right, he, nor anybody else, any need to worry about any afterlife. Senator Sanders by both his questions to and assertions about fitness for office of Mr. Vought has applied an unconstitutional religious test for office. Sanders is not fit to hold public office, and should resign, or be expelled from the Senate.
