I think Dash-hole realized that he comes across as sort of a weasel - after his blunders attacking the war strategy and tax cuts, he (IMO) decided he will be more effective keeping out of the spotlight.
As for El Loco Poco Dicko, I don't know - I actually kind of like watching him, because his face always turns beet red when he is on one of his rants.
I only caught The George Stephanopoulos Show starting with the final minutes of the segment with King Abdullah II of Jordan.
It looked, to me, like George S. had no (current) US big-wigs on the program.
Are they boycotting George? Will the big-wigs be on This Week, next week, when Sam and Cokie are back?
