You are right on the various possibilities you suggest; but would lean towards the above as being an overriding factor. . .and you are right as well, we are spoiled with a greater press from Fox News and of course FR.
Still, you would think, hope. . .expect more of Buchannan despite the limitations of MSNBC .
Just went to his/their website to see if Scott has been a repeat topic and he has not.
They invite e-mails and have a chat room. . .do not have time now; but that may be a good place to go and update Buchannan and educate these MSNBC folks and fans as well. . .
