Published October 28, 2026

Bernie Bot, also spelled Berniebot, is a slang term for automated accounts that posed as hostile Bernie Sanders supporters to spread misinformation and provoke arguments online. Originally coined in 2015 as an insult for Sanders fans, the word shifted meaning after 2016 reports tied inflammatory pro-Sanders accounts to foreign disinformation operations1. By February 2019, Daily Dot was publishing explainers on how to tell a human Bernie Bro from a Bernie Bot during the 2020 Democratic primary4.

Overview

The word carries two meanings that collapsed into each other between 2015 and 2017. In its first life, calling someone a Bernie Bot meant accusing them of parroting Sanders talking points without independent thought, with the robot imagery doing the sneering work3. Opponents on Facebook and later 4chan used it this way as a drive-by insult during the Democratic primary against Hillary Clinton3.

After March 2017, the term picked up its second and more technical sense: an actual automated account, often traced back to foreign operators, posing as a Sanders die-hard to pump out memes, fake stories and bait replies1. A typical Bernie Bot post of that period pushed anti-Clinton conspiracy content, including the fake story about Clinton using a body double, and fed it into pro-Sanders Facebook groups to drive sharing2. The two meanings never fully separated, which is part of why the Daily Dot felt the need to spell out the difference in 20194.

The insult version of the term predates the bot version by over a year. On October 20th, 2015, a Facebook group called "Bernie Bots" launched, framing Sanders supporters as robotic followers with no opinion of their own3. On March 14th, 2016, an anonymous poster on 4chan's /pol/ board used "berniebot" to attack someone criticizing Donald Trump, which locked the word into general right-wing and anti-Sanders usage6. An Urban Dictionary entry by user theveryliberalhomosexual followed later that year7.

The meaning flipped after March 2017, when HuffPost reported that the admin of a pro-Sanders Facebook group had seen a flood of inflammatory new supporters starting in June 2016, later traced by a private investigator to users based in Macedonia and Albania who were pushing fake news and pro-Sanders memes1. By the end of that month, the Senate Intelligence Committee confirmed Russian intelligence had used Sanders supporters as unwitting agents for a parallel disinformation push2.

How It Spread

Raw Story's reporting on the Senate Intelligence testimony cemented the automated-account meaning, quoting the same group admins describing anti-Hillary memes about body doubles and murder plots pouring into their feeds from suspected Russian accounts2. One admin described the influx as a tsunami of misinformation1. Those details gave the word Bernie Bot a specific referent beyond name-calling.

As the 2020 primary opened, Politico reported in February 2019 that a fresh coordinated attack was already running against Democratic candidates, including pro-Sanders bot activity designed to sow discord inside the primary itself5. Days later, warnings traveled across Twitter: user @missmayn posted a widely shared thread arguing that much of the 2016 Bernie Bro abuse had come from Russian disinformation accounts and asking real Sanders supporters not to repeat the pattern, picking up more than 490 retweets and 3,600 likes within three days8. User @igorvolsky posted that an account he had publicly flagged turned out to be a bot, though he noted the same style of reply was coming in from real Sanders supporters too9.

The Daily Dot published a how-to-tell-the-difference piece that same week, which is where the term got its most explicit public treatment4. After the 2020 primary ended, the word mostly fell out of active use outside retrospectives.
