[8] After the 2020 elections, Pepper announced that he would step down as Ohio Democratic Party Chairman at the end of the year.

[7] The Wall Street Journal wrote that Pepper "writes with flair and insider knowledge of everything from gerrymandering to arrogant D.C. press aides" and "With speed and savvy, 'The People's House' emerges as a sleeper candidate for political thriller of the year".

[11] Bill Clinton said of The Voter File: "Pepper comes through again with this clever tale of how cyber sabotage of elections, coupled with highly concentrated ownership of traditional media operations, can undermine American democracy".

[13] Writing in 2022 for Salon, Paul Rosenberg called Pepper's 2021 work Laboratories of Autocracy "arguably the most important [book]" among the "booming literature on the erosion of democracy in America" and stated that the book "brings the subject down to earth, connects democratic erosion to corruption and the decline in America's quality of life, and provides a wealth of ideas about how to fight back to protect democracy".

[14] Pepper emphasizes these potential solutions in a Substack publication he has named "Pepperspectives", such as "'2025': Anticipating What's Coming ...In Order to Stop the Worst of It" on November 8, 2024 and in interviews by political commentators concerned about protecting democracy, such as "Happy Hour 181 - Texas In The Second Trump Era" by Progress Texas in late 2024.
