The head of the DNC (and Hillary's former campaign manager) giving debate questions to the Clinton campaign is truly outrageous, and it is only the media's extreme hate for Trump that is keeping this from getting more attention. But I agree with your point that it is not damaging her.
The media's extreme hate for Trump? They used to love him. He was, and still is, great for ratings. And his free media attention is a big part of why he won the primaries. But he keeps saying increasingly shocking, vile and dangerous things, and it's the people working for the media, as well as everybody else (even people from his own party) who are getting extremely disgusted with him.
Don't paint this as if it's just the media. It's Trump.
People were distracted by the pussy thing - which was not coincidentally released on the same day.
Most people have no idea what was even in those emails and most of the media I read made a point to say that there was nothing damaging in there (cherry picking the most mundane things they could).
There wasn't anything too surprising to people who hate Hillary Clinton (yes, she's in the pocket of wall street) and supporters and most of the mainstream media (MSNBC, CNN, NYTimes, etc.) didn't pay any attention.
I read a bunch of the emails and there wasn't anything significant in there unless you count cherry-picking quotes and willful misunderstanding. At best there are some ambiguous things that could be interpreted certain ways.
tl;dr: There is no smoking gun. People say things in private emails they wouldn't discuss in public, NEWS AT 11!!!!!
P.S. It wasn't "that pussy thing". It was Trump bragging that he pushes women into sexual encounters he knows they don't want and gets away with it because he's famous and rich. I like how the right pretended everyone was upset about some foul language though or that it was just "locker room" talk. If Trump had said "oh she's so hot, I'd love to fuck her" no one would have cared because that is locker room talk. What Trump said was in a different league.
If it was so basic, why did the head of the party email the campaign the exact question? She must have thought it was important, otherwise why put your career on the line
* She admitted to having a "private" (real) policy position and a "public" one (lies).
* Bits of her speeches to Goldman came out and she basically said "we were way too hard on you guys" and "we need to listen more to you guys to help prevent another crisis".
* She mentioned that she basically wanted a hemispheric free trade & freedom of movement zone.
Of course, apparently it's not the done thing these days to talk about policy scandals that actually affect us during a Presidential election.
How is the first one a smoking gun? She was quoting someone else. Lincoln, I think.
Her ties to Wallstreet are hardly a surprise. It sucks, but we already knew that she's probably not going to do what needs to be done to Wallstreet. But there's no reason to believe that Trump is going to do any better, and on almost everything else, Clinton is still a lot better, or at worst less bad.
I think she's more alluding to something like the EU common market. NAFTA, CAFTA, TPP and TTIP don't do anything about freedom of movement, and do a lot about a ton of other things that have nothing to do with that.
The pussygate tape came out before the Wikileak emails [1] which argues, if you're rational, that the timing was co-incidental or, if you're conspiratorial, that the Clinton campaign had a mole inside of Wikileaks who had just enough access to make them aware of the leak but not enough to stop it.
