Of course, their definition of what constitutes a "junk political propaganda site" is entirely subjective, so this is a completely meaningless study. I consider CNN to be junk political propaganda, how do the statistics vary when you include THAT? If they really wanted to make a meaningful study, they would publish statistics for several definitions of "junk lists", collected from varying perspectives. I suspect that would just be another way to show the stark polarized digital corners we've all painted ourselves into.
As is, this is, ironically, more political propaganda....
