Why is the annointed on Obama getting a free pass on talk shows and jokes are taboo?

jay Leno and Letterman are caustic concerning conservatives but give their comrade democrats a free pass then go and complain about FOX network being biased and wanting to limit free speech on radio talk shows. The main steam media has been in bed with Obama from the git go never giving him hard ball questions. He was never questioned about his association with Bill Ayers the Weatherunderground bomber or his preacher Jermiah Wright who hates America.
