MSNBC and CNN have improved ever so slightly on PunditFact’s TV network scorecards, while Fox News has moved a touch in the opposite direction. PunditFact, a sister site of PolitiFact dedicated to fact-checking pundits and talking heads, last looked at its network scorecards in September. The scorecards measure statements made by a pundit or a host or paid contributor on a particular network. They do not include statements made by elected leaders, declared candidates or party officials.
