It's only a matter of time before Trump starts attacking Hillary with TV ads over her various scandals, email and otherwise.
Once he does that, those scandals will leave the domain of reality and enter the domain of "right-wing talking points".

That means that mentioning those scandals in anything other than a very non-judgemental way (i.e. can't draw conclusions from the facts) will mean you are "engaging in right-wing smears", and thus make you subject to banning.
Developments concerning those scandals (i.e. new evidence being discovered) will only be discussed with extreme skepticism. After all, they are just right-wing smears anyway, right?

If Hillary's numbers continue to sag and she falls noticeably behind Trump in the polls, then this reaction on GOS will get more extreme and maybe even hysterical.
Questioning loyalty to party will be the first call of duty. FP diaries about how eviiilll Trump is will be even more pronounced.

Obviously the first people that will be blamed are independents and progressives that support Bernie.
Any discussions about the weakness of the Dems candidate will wait until after the election.
Any discussion about why people would support Trump, other than for reasons of racism and sexism, will be beyond the pale.

Basically, now is not the time for rational introspection of the Democratic party.
