Rich Lowry of National Review explores Democrats’ criticism of FBI Director James Comey.

Before Democrats burn James Comey in effigy, they should think about how the FBI director came to have an outsized influence in the election in the first place.

It’s not something Comey sought or welcomed. A law-enforcement official who prizes his reputation, he didn’t relish becoming an object of hate for half the country or more. No, the only reason that Comey figures in the election at all is that Democrats knowingly nominated someone under FBI investigation.

Once upon a time — namely any presidential election prior to this one — this enormous political and legal vulnerability would have disqualified a candidate. Not this year, and not in the case of Hillary Clinton.

The country has clearly lowered its standards in this election, and Donald Trump’s madcap candidacy provides evidence of that almost every day. But Hillary’s nomination was itself an offense against American political norms and an incredibly reckless act. And the Democrats were supposed to be the party acting rationally.

Clinton effectively locked up the nomination in June and wasn’t cleared of criminal wrongdoing by the FBI until July. What if she had been indicted? Would Democrats have run her anyway? Would they have substituted in a 74-year-old socialist who had lost the nomination battle, or someone else who hadn’t even run? Any of these circumstances would have been unprecedented, but Democrats risked it.
