It’s called “nooooo, we TOTALLY vetted Obama as the main stream media!!!!!! Why would you say otherwise????”
There is a semi-famous tape of a conversation between Tom Brokaw and Charlie Rose, I believe, wherein they both ask the question, “What do we know about this man?”. They come to the startling conclusion that we don’t know very much. This conversation took place shortly before or after Election Day, 2008. So much for vetting.
