I think you misunderstand and I already changed the article from what it said before Before it listed her in shorthand as Chase Smith like Chase Smith did this and Chase Smith did that There s no doubt that she used the name Margaret Chase Smith in lieu of Margaret Smith which I have never heard but her last name was always Smith and she was Senator Smith not Senator Chase Smith some books have referred to her as such but I can t find anything from her or the US Government The sources you provide show that she was categorized as Smith Margaret Chase with Chase being treated as a middle name as was is common for many married women not a part of her surname Thus I think the shorthand for Margaret Chase Smith remain simply Smith or Senator Smith or what have you and Chase Smith Unless of course I m still missing something
