If the autopsy takeaways are that third parties and Comey were the
problems, then the lessons Democrats will take ahead of 2020 are that
they need to blast Jill Stein and Gary Johnson into outer space and
prevent FBI directors from releasing vague letters, and everything
should be fine. Even if Clinton had eked out narrow wins in Michigan,
Wisconsin, and Pennsylvania, the Democratic Party’s poor showing against
a Trump-led Republican Party would have signaled something was
seriously wrong with the patient. Parties can never eliminate external
factors. All they can do is ensure that the foundation’s strong enough
to withstand them.
