He is definitely good at what he does.
Maybe we could get Rumsfeld to fill in for Ari for a few months, I would give Rumsfeld 1 week and Terry Moran would go back to his former career..... (Drag Queeen),
Helen Thomas would have water thrown on her and she would melt live on C_Span,
David Gregory would commit "Harry Kerry" in mid sentence and.....
Ron Fournier would go back to his old job in the White House Press Corp only to become Donald Rumsfeld's B*tch :-)
