One could, but if one resigns I suggest that one is less likely of being able to win one's own seat. I would not recommend it to the Senator as a certainty, shall I say. In the other House, however, one would stand in one's own constituency and be able to ask the people who gave the original mandate, and those alone, to reconfirm that mandate, if one was so minded.
