The biggest and most imrpessive difference between CNN and Fox News is the number of viewers. That’s what matters in the news business. Also, Obama’s administration wouldn’t be going on the attack if Fox News was weak and effete.
I believe cnn viewership us under-reported in these polls. Cnn is the overwhelming network of choice for public places where people gather: airports, hotel lobbies, office building lobbies, etc. Are these viewers captured?
