It is not just BIG MEDIA.
I am currently visiting in a highly Republican area. When there was going to be the Democratic Caucus for the first time in history in Nebraska. The local paper editior/owner who controlls 2 papers and 1/2 the county that way. DID NOT Print one word about it, or when or where, it was going to be held.. He had received 2 press releases about it. But not even one small paragraph.
However, he managed to take the entire front page and 1/2 the back to promote and praise the "Anti Abortion March" Including loads of pictures, etc.
That is the unbiased or liberal media? What a joke.
