Watching C-Span from 7 to 10 every am, i quickly understood that visiting guests who were interviewed as authorities on a subject were presenting slanted views according to the "foundation" that they were representing. Two of these, the Enterprise and Heritage Foundations, were on the right of the political spectrum. But there are dozens more that I have not been able to place. For the average viewer who has no clue whether the speaker is in the employ of a certain institution with a message to sell,s/he cannot possibly estimate the validity of the guest's viewpoint.
If there is a blogger who could identify for me the position taken by these foundations, even newspapers, that would be a great help. I do know that the Washington Post and NY Times are considered to be left leaning while the Washington Times and LA newspaper are on the right. The Boston Globe, am not sure. Thanx for any input.
