::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.
