Very sorry to har this, I read her wikipedia bio, she seemed to have gotten breast cancer in 2002:
wikipedia For some reason, in my mind, I associate Cokie and George Will together, they must have been regulars on ABC's 'The Week":

You can imagine, it's
the leading story at NPR. She'll certainly be missed.
I'm sure there will be a number of tributes that come out for her.
BTW, Daughter of
Senator Boggs - (D) Louisiana.
A lot of history in all of this too.
Per Senator Bogg's wikipedia entry, on the plane he was in that went down:
Speculation, suspicions, and theories
The events surrounding Boggs's death have been the subject of much speculation, suspicion, and numerous conspiracy theories.[citation needed] The theories often center on his membership on the Warren Commission. Boggs dissented from the Warren Commission's majority who supported the single bullet theory. Regarding the single-bullet theory, Boggs commented, "I had strong doubts about it."[21] In the 1979 novel The Matarese Circle, author Robert Ludlum portrayed Boggs as having been killed to stop his investigation of the Kennedy assassination.
In case, one didn't know this.
Also, thanks to Mountaineer who certainly already provided some of this info.
