Conversely we have been hearing this would go away quickly since the first week of March 2015.
Think back, we have seen: revelation that the emails were entirely deleted (and at one time believed wiped), the server seized, a criminal referral to the FBI by two IGs, an FBI investigation, Hillary's trust/honesty numbers drag her down (though not all the way) into a primary fight vs a supposed <10% candidate into March 2016, her IT guy pleading the 5th and taking immunity, Hillary submitting an affidavit to federal court, 50 FOIA cases being opened/reopened, the investigation repeatedly expand to three states, State, the Foundation and even Romania, Hillary being asked in a debate and in several interviews if she herself will be indicted, and over 30,000 emails produced via FOIA with over 2100 classified documents and something like 200 documents Secret or above including some Top Secret and even above Top Secret.
It's really been something.
