Boo. Last week, FBI Director James B. Comey decided to scare up this election’s October surprise, writing to inform 16 congressional committee chairs and ranking members that the FBI had discovered e-mails in an unrelated investigation that potentially could be linked to the probe of Hillary Clinton’s e-mails. Subsequent leaks led The New York Times to report that the e-mails were found on a computer belonging to Anthony Weiner, the disgraced ex–New York congressman and estranged husband of Huma Abedin, Hillary Clinton’s closest aide and “surrogate daughter.”

Frenzy ensued. Donald Trump immediately embraced the agency he had excoriated; the Clinton campaign attacked Comey directly. The New York Post called it the “stroking gun.” “Could Anthony Weiner’s E-Mails Cost Hillary Her Job?” asked the ever-hyperbolic Larry Kudlow. Livid Democrats opted for Kremlin-baiting. Former Democratic National Committee chair Howard Dean, a Clinton surrogate, tweeted that Comey, a Republican, “put himself on the same side as [Vladimir] Putin.” Senate leader Harry Reid charged that Comey had “explosive information” about “coordination” between Donald Trump and “the Russian government.”

Early polls suggested that most Americans would not be influenced by the news, but some might. In a race that was already tightening—as both major candidates firmed up their support in their own parties—partisans on both sides escalated the spitball volleys.
