Nina Tomasieski logs on to Twitter before the sun rises. Seated at her dining room table with a nearby TV constantly tuned to Fox News, the 70-year-old grandmother spends up to 14 hours a day tweeting the praises of President Trump and his political allies, particularly those on the ballot this fall, and deriding their opponents.

She’s part of a dedicated band of Trump supporters who tweet and retweet Keep America Great messages thousands of times a day.

“Time to walk away Dems and vote RED in the primaries,” she declared in one of her voluminous tweets, adding, “Say NO to socialism & hate.”

While her goal is simply to advance the agenda of a president she adores, she and her friends have been swept up in an expanded effort by Twitter and other social media companies to crack down on nefarious tactics used to meddle in the 2016 election.
