Amarnath Gupta, a research scientist at the San Diego Supercomputer Center at the University of California at San Diego who monitors social media activity, said he’s also seen a recent surge in Twitter activity negatively targeting three candidates — O’Rourke, Harris and Warren.

That increased activity includes a rise in the sheer volume of tweets, the rate at which they are being posted and the appearance of “cluster behavior” tied to the three candidates.

“I can say that from a very, very cursory look, a lot of the information is negatively biased with respect to sentiment analysis,” said Gupta, who partnered with Guardians.ai on a 2018 study.

According to the Guardians.ai analysis, Harris attracted the most overall Twitter activity among the 2020 candidates it looked at, with more than 2.5 million mentions over the 30-day period.

She was also among the most targeted. One widely seen tweet employed racist and sexist stereotypes in an attempt to sensationalize Harris’ relationship with former San Francisco Mayor Willie Brown. That tweet — and subsequent retweets and mentions tied to it — made 8.6 million “potential impressions” online, according to Guardians.ai, an upper limit calculation of the number of people who might have seen it based on the accounts the cluster follows, who follows accounts within the cluster and who has engaged with the tweet.

Another racially charged tweet was directed at O’Rourke. The Twitter profile of the user where it originated indicates the account was created in May 2018, but it had authored just one tweet since then — in January, when the account announced it had breaking news about the former Texas congressman leaving a message using racist language on an answering machine in the 1990s. That tweet garnered 1.3 million potential impressions on the platform, according to Guardians.ai.
