The author is mistaken. Liberal journalists do not outnumber conservatives ones by a margin of four to one. They outnumber conservative journalists by about ten to one.
Per my observations of the MSM, you're being overly generous, but hey, that's a conservative trait, and I forgive you for it.
Perhaps the author was only considering Leninists snd Stalinists as “liberals,” the rest being “conservative.”
When it come to spewing Palin vitriol, I often have a hard time distinguishing between some so called conservatives writers and those of the far left. It is like she is a left/right equal opportunity target for lies, ridicule and hate.
Is it group think or herd instinct? I have come to think of it as the fear factor, of a threatening force they cannot control.
