In surveilling Carter Page, the FBI had every reason to know it was surveilling an inconsequential non-spy, and did so based on a warrant that falsely characterized a Yahoo news article. Its suspicions of George Papadopoulos were based on drunken gossip about Hillary’s emails when the whole world was gossiping about Hillary’s emails.
The FBI’s most consequential intervention of all, its last-minute reopening of the Clinton investigation, arose from “new” evidence that turned out to be a nothingburger. There is a term for how all this looks in retrospect: colossally stupid. Democrats now have a strong if unprovable case that Mr. Comey changed the election outcome. Mr. Trump has a strong case his presidency has been hobbled by unwarranted accusations. Americans harbor new and serious doubts about the integrity of the FBI.
