The Media Elite a book by Lichter, Rothman and Lichter reported the results of their survey. It was a 1986 book, granted it is older information, but still true. Their survey of 240 journalists from CBS, ABC, PBS, NBC, CNN, etc. showed that the suppoort of the Democratic candidate NEVER dropped under 80%.
In 1995, Ken Walsh from US News and World Report asked his fellow White House reporters to fill out a survey. 28 returned the survey. In 1992 the admissions showed 9 voted for Clinton, 2 for Bush and one for Perot.
I just found that on the internet after a few minutes research, the information is out there. Does that suffice for facts?
