Once Trebek retires, would it be

One of the clue crew members?

A former competitor? James Holzauer (sp?)? Brad Rutter? Ken Jennings? Buzzy Cohen?

Perhaps a journalist who knows history, geography, and other languages? I think of Megyn Kelly but seems like people dislike her. I don't know anything about her so I don't know if she would do well or not.

I would love to see Ken myself.

Anyone else have thoughts?
