Truly horrible and tragic news. Our condolences to Andrei and her entire family.
Beth was a brilliant, inquisitive, perceptive, generous colleague, who worked as hard as anyone I know (I recall getting her the edit of an ELJ article on Christmas Day, and she responded the same day. When I asked her if she was taking the day off, she said she never took a day off). No matter how busy she was, she was always ready to give comments on a paper, or sound advice about law and academia.
I invite election law and legislation scholars to send me their remembrances of Beth, which I will post on the blog.
Update: I am posting remembrances of Beth at this link.
