The scenario I would hope for is that China (or Russia, or anyone) has indeed hacked her e-mails, and they keep their powder dry until she has testified under oath about the e-mail situation. Then, the e-mails get posted to some server, somewhere, a la WikiLeaks, and kaboom - no more Hillary. I think she is concerned about this possibility, and it explains her highly constrained comments and answers in public so far.
The problem with this scenario is that is assumes that the holder of the information would rather see Hillary knocked out of the election, when in fact they may just want to leverage the threat to control her once in office.
DEMAND THAT CONGRESS ACT NOW---CONTACT CONGRESS HERE:
http://www.contactingthecongress.org/
==============================================
Demand that Congress launch multiple investigations into Hillary’s State Dept tenure together w/ her confidantes (like Huma Abedin):
<><> expense accounts,
<><> use of federal credit cards,
<><> their participation in the State Dept's disbursement of funds to "private contractors;"
<><>collusion and conspiracy with the Clinton Foundation--using classified info as an instrument for fund-raising.
Hillary's official calendar, and her contact with foreign leaders. will tell the tale of donations to the Foundation....with the Clintons profiteering off secret intel.
Top secret FBI/CIA files may be involved.
By the way, Hillary is not as beloved as people think. Does anyone remember how her campaign literally imploded by the end of 2007? In short, her campaign is going to be running into a lot of trouble soon just like what happened to Sepp Blatter at FIFA.
