Shortly after Trump’s inauguration in January 2017, I joined the local (Lincoln Square, Chicago) chapter of Indivisible, a grassroots organization focused mainly on defeating Trump in 2020. My experience of canvassing for Democratic candidates in 2018 led me to believe that it would be interesting to keep a record of voter sentiment during the upcoming 2020 campaign. So I decided to keep a diary—a political diary—something I’d never done before. I kept the diary from January 1, 2020, through January 20, 2021. When Trump decided to run again in 2024, I decided to keep a second diary during that election year, as a companion to my 2020 chronicle. As before, I tried to keep abreast of current political events and I included my thoughts about these in the diary. Also included are excerpts from a “Weekly Update” that I regularly sent to Indivisible Lincoln Square members, with headlines under various topics such as environment, social justice, healthcare, etc. How Trump managed his comeback triumph in 2024 is a mystery for historians to solve. There is a long tradition of writers offering "materials for history." In that spirit this diary is being offered, complete with grammatical errors and repetitions—just as it was written each day. Perhaps it will help solve the mystery.
