Several other MSM reporters were tweeting on this yesterday and I ain’t just talking Shuster. These tweets were done almost at the exact same time. Heck, they probably all post at Kos.
It’s pretty widely known that the state-run media uses Puffington Host (misspelling intentional) as a legitimate source, and a “must-read” for setting the daily/weekly news agenda the way The New York Times once was.
So yeah, I wouldn’t be surprised if they all read Kos multiple times a day.
