If when Diane Sawyer leaves GMA, who will take her seat?

“First in line for the morning desk is Campbell Brown, the snappy brunette news junkie that NBC can no longer afford,” according to the Observer’s Rebecca Dana. Brown’s contract is up next summer and “ABC is in discussions.”

The story says Kate Snow and Elizabeth Vargas are “also liminally in the running.”

That’s created a stir at ABC, leading someone with knowledge of the situation to e-mail TVNewser and say: “Kate Snow is way ahead of Campbell Brown should there be a need to fill a position at GMA.”
