Well honestly, it is difficult to have an open debate of ideas and policy, and then hash it over in the media, when one side isn't taking any position, and has no actual policies. Clinton has gone on and on about programs and policies she wants to push, and people say, "Ok, got it", then turn to the other side for a rebuttal, and get... babies being ejected from speeches, or abuse of fallen soldiers' families, or whatever Lord Orange comes up with today. Right now there should be a healthy, (and, because it's the 2000's) nasty, public policy debate going on with talking heads on both sides shredding the other side's positions, and proposing alternate plans in detail. But you can't play ball unless the other team gets on the field. (Honestly, I think this week we are going to see a message-binge from the Clinton camp. If they don't take this total vacuum of ideas and fill it up with their own, they are missing a HUGE opportunity! If they just blanketed their policies and programs over every media outlet this week, there is nothing Trump could do but spend the next several months responding to her detailed policies... and he SUCKS at that. It's be a total wipeout, come Nov.)
That all sounds pretty logical and when you put it that way, I'm kind of surprised Hillary and co. aren't taking the opportunity to steer the conversation. If I had to guess, it may be that they're just worried about third party candidates starting to throw their opinions in, but then again, most of the time they're not paid a lot of attention to anyway so I don't see that being much of a risk.
