I just read through the big NYT piece on FBI investigations in the 2016 campaign. My big takeaway is that the FBI is afraid of Republicans in a way that they’re simply not afraid of Democrats. I’m not saying that they’re wrong to feel this way, just that it’s a fact.
[W]ith polls showing Mrs. Clinton holding a comfortable lead, Mr. Comey ended up plunging the F.B.I. into the molten center of a bitter election. Fearing the backlash that would come if it were revealed after the election that the F.B.I. had been investigating the next president and had kept it a secret, Mr. Comey sent a letter informing Congress that the case was reopened.
Congressional Republicans were preparing for years of hearings during a Clinton presidency. If Mr. Comey became the subject of those hearings, F.B.I. officials feared, it would hobble the agency and harm its reputation. “I don’t think the organization would have survived that,” Mr. Steinbach said.
Comey made the announcement about potentially reopening the Clinton case because he was afraid of Republican reprisal. Full stop.
Fear of the right wing is an important part of the ethos of modern Washington, and it’s what swung this election.
