Actually, it always surprises me that Face the Nation is able to attract such high-quality guests. I never watch it, but must say bagging Siniora and Peres for today's edition is quite impressive.
Why do such high-level newsmakers appear on the least-watched news program?
All first come, first served. They may not know the ratings of each show. Both of them were on with almost all networks the past few days. I think people like Nethanyahu would be much more interesting (even Israeli PM Omert says this in JPost).
