The media are Clinton lap dogs and/or Clinton attack dogs. They will tell any lie to help Clinton.

Yep

But why are so many Republicans attacking Trump and refusing to say anything negative about Clinton

Three Reasons
1. He was wrong to inject ethnicity and he seems incapable of repentance or correction. It was gross negligence on his part.
2. He is not pivoting successfully to take on Clinton after her speech. Instead, nhe made it about his court case, not her corruption, not her gross negligence handling classified emails, but his court case and the ethnic heritage of the judge. It is all everyone is discussing and laughing about.
3. He is dropping in the polls after leading ever so slightly. They sense electoral disaster from his mistakes. Perhaps he can recover but it seems a long shot. There just aren't that many persuadable voters left.
