You've been studiously ignoring the fact that DOJ officials former and present, Democratic and Republican, are up in arms about Comey's decision because it compromises the integrity of the democratic process (what's left of it). Comey's motivations are beside the point.

Once again resort to the "both sides" truism obscures the crux of the matter. The FBI is not to file a case or comment on an ongoing investigation 60 (SIXTY!) days before a presidential election, much less 10 or 11. Because even with the purist of motivations, it has both the appearance and the effect of influencing an election.
