Let's be clear, there's no evidence that the Russian government actually influenced the outcome (hacks aside, but any information released from those hardly shifted the balance of the election) of the election in any material way.
that is not necessary to be disturbed in a meaningful way.
the result of the leaks - which were aimed at a specific goal - were the major campaign topic for over a month.
even if not even a single vote has been changed cause of those leaks (not likely), the potential wish to undermine the election and the DIRECT communication between russian state actors and the trump campaign are reason enough for small-l liberals to worry.
