I think "IF" she survives, Trump will be one candidate not making it all about those emails as it will be plain that she has survived that issue, and Trump is not running as a bible thumper, you don't see Trump making Gay Marriage, Abortion rights, or Planned Parenthood as his key issues. THAT is one of the main reasons Trump is so far ahead right now.  

Now if Hillary runs against any other Republican besides Trump, whether that be Carson, Rubio or Bush. I can see where social issues will serve her well, especially if the Republican candidate falls into the trap of campaigning on something stupid like overturning gay marriage.
