doesn't cnn run opinion pieces sometimes? i think that it might have been multiple authors with differing opinions being allowed to write their what they thought. sort of to give different views on topics?

Author of first opinion piece worked for Hillary Clinton.
Author of last opinion piece works for Cato Institute.
OMG the hypocrisy of liberals and conservatives having different opinions.

When they have two different pundits on Face the Nation saying different things, it doesn't mean that CBS is contradicting itself.
