Rush had an interesting caller about people who gravitate to natural leaders, and said Trump was such a person. The caller pointed out that nobody is covering Hillary because there is nothing new to offer.
Right now Hillary is just pretending to be running. She does the bare minimum necessary to appear to be in the race but nothing more. She knows it's all for show at this point, that the rigged nomination is hers and she's pacing herself. And probably a smart strategy because to see and hear Hillary is to innately dislike her.
But it's true that when she does show up it's just warmed over rhetoric from the same old playbook. Boring.
