I don't think Hillary Clinton's troubles are ever going to go away. Whether it is her emails or the Clinton Foundation or any number of things.
Even if she get's elected, she is going to be dogged by one thing or another in a probably unprecedented way.
It will never go away and it will likely tarnish the whole presidency for as long as she is President
If only the Democratic Party had a good candidate to put up.
I think a danger is that people now, in greater numbers, realise this and vote for Trump
Anyone pathetically dumb enough not to know that Trump would forever tarnish the presidency and the world's view of the American people on the day he was elected to it, infinitely more than Hillary ever could, is already committed to Trump. In addition to being as dumb as his supporters, Trump is a lifelong rapist, misogynist, rabid racist, and white-collar criminal and details of his crimes would emerge every day during his presidency. In fact, just by being a close second, Trump has already tarnished the presidency.
The only danger of these orchestrated by the GOP masquerading as the FBI is if it hurts turn out among those who would vote for Hillary, if they got to the polls.
