CHICAGO (AP) — 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.
