This two-day old CNN clip has gotten around, but it has something new I missed on Friday. Jack Cafferty‘s rant about Sarah Palin is angry but unexceptional — he’s expressing a fairly common reaction to Palin’s performance during her recent Katie Couric interview. What stands out is Cafferty’s rebuke of CNN anchor Wolf Blitzer when the latter tries to explain away Palin’s shoddy performance due to having had to cram in a lot of information in a short time frame.
