I suspect that Bernie took the nominee's religious beliefs that non-Christians can't go to heaven personally.  Bernie was raised Jewish,  although he appears to be an agnostic now.  Either way,  he won't make it into the New Testament heaven without accepting Jesus.  Perhaps there is a different version where his beliefs are welcome.  The Hebrew Garden of Eden,  the Vikings Valhalla,  the Celtic Otherworld,  the Irish Tir Na Nog, or the Greek Elysium, all have entrance requirements.  But his line of questioning was out of line in a confirmation hearing.
