Hillary's handlers are obviously not letting her get put into a situation where she could be put on the spot and have to think on her feet. She's only doing appearances where everything is carefully controlled and scripted so they can keep her from having to answer for the myriad of scandals that surround her. That's why the debates are going to be so critical if she doesn't manage to avoid doing them all together. If Trump can avoid getting set up with the debate format and biased moderators like Candy Crowley then he should be able to wipe the floor with her. She's got far too much baggage and he's not afraid to play hardball unlike Mitt Romney. I think she's going to come up with every excuse under the sun not to debate him and her handlers are going to keep access to her tightly controlled until the election. She's essentially going to try to run out the clock and not give anyone a chance to back her into a corner on all her scandals.
