I must disagree, much like Professor Turley who is also a lib, I have often found Halperin to be insightful, and about as fair overall as you can expect from someone with his experience.
I don't want to watch an echo chamber, since those types are often insincere and over time will disappoint (ie most Fox News talent, Michael Savage ).
Have you watched his show on NEWSMAX?
Only Turley I like is Steven Turley.
