Trump has long been an authoritarian. Anne Gearan and Josh Dawsey report that “Trump has been fixated on overturning the [2020] election for weeks, making hundreds of calls to allies, lawyers, state legislators, governors and other officials and regularly huddling with outside lawyers Rudolph W. Giuliani and Sidney Powell, Chief of Staff Mark Meadows and others” (https://www.washingtonpost.com/politics/trump-election-capitol-building).
According to The January 6 Report of The House January 6th Committee,
“the Trump complaint about a rigged election involved ‘62 separate lawsuits between November 4, 2020 and January 6, 2021, calling into question or seeking to overturn the elections results. Out of 62 cases, only one case results in victory for the President Trump or his allies, which affected relatively few votes, did not vindicate any underlying claims of fraud, and would not have changed the outcome in Pennsylvania” (p. 210).
