Have presidential election results been challenged in any other elections besides the 2020 election?

Yes, presidential election results have been challenged in other elections. In 2000, the Bush v. Gore ruling by the Supreme Court allowed disputes over the recount results in Florida to halt the machine recount. This resulted in George W. Bush being declared the winner of Florida and therefore the entire 2000 election. In 2004, a lawsuit was filed against the Ohio Secretary of State alleging that certain voters were improperly challenged in some counties, affecting the results in the state and the entire election. Additionally, the 2008 election saw a variety of challenges, including allegations of voter irregularities and charges of racism, leading to a prolonged legal battle over the election results in the weeks following the election.  Finally, in 2020, Trump's legal team unsuccessfully challenged numerous ballot counts in certain key states on the basis that the processes of accepting and tabulating votes was riddled with errors and systematic bias.
