I remember thinking Bassem Youssef would take over for Stewart. It might be interesting to see if he becomes a correspondent or part-time host.

He definitely took the show to a hard left turn. The correspondents were also a mixed bag. I hope that that they do a clean slate with the replacement, so yes, I think some changes will be needed.
