A few hours after polls closed in Kentucky last Tuesday, a Twitter user writing under the handle @Overlordkraken1 posted a message to his 19 followers saying he had “just shredded a box of Republican mail-in ballots.”

It was clear that the Kentucky governor’s race was going to be excruciatingly close, and that the Republican incumbent, Matt Bevin, could be headed to defeat. But just in case anyone missed the significance of the destroyed-ballots claim, @Overlordkraken1 added a final touch to his tweet: “Bye-Bye Bevin,” he wrote.

For those eager to cry fraud as a reliably red state leaned blue, the fact that @Overlordkraken1 did not appear to be in Kentucky — Louisville was misspelled in the location tag on his tweet, for one thing — was not going to get in the way of a useful narrative. Nor was Twitter’s decision to suspend his account.

Within hours of @Overlordkraken1’s tweet, as it became apparent that Mr. Bevin was trailing in the vote tally, hyperpartisan conservatives and trolls were pushing out a screenshot of the message, boosted by what appeared to be a network of bots, and providing early grist for allegations of electoral theft in Kentucky. High-profile right-wing figures were soon tweeting out their own conspiracy theories about the election being stolen — messages that were in turn pushed by even more trolls and bots — and the Bevin campaign began talking about “irregularities” in the vote without offering any specifics or evidence.
