For the 460,000 Twitter followers of Praying Medic, one of the most prolific posters of the QAnon conspiracy, the US election is not over. His timeline is peppered with claims of electoral fraud, alongside retweets from President Donald Trump.

“Anyone who thinks Donald Trump has no chance of winning reelection hasn’t thought through all the contingencies to their logical or likely end,” Praying Medic said in a tweet earlier this month. “Biden’s only hope of winning was convincing Trump to concede. He failed.”

But despite his optimism, the rightwing theory has been dealt a heavy blow by Joe Biden’s US presidential victory. Experts warn, however, that it could still cast a shadow over global politics for years to come.
