Many Democrats think that the 2016 election result was rigged

Previous studies have found that after an election, supporters of the losing candidate tend to be more likely to believe that votes were counted improperly. So how did Donald Trump's claims that the 2016 election was 'rigged' ahead of his own victory influence voters' perception of the election's integrity? Using national survey data, Betsy Sinclair, Steven S. Smith and Patrick Tucker find that Republicans gained confidence in the vote after Trump’s election win, while Democrats’ confidence fell. This effect was even more pronounced among bettereducated Republicans and Democrats who identified most strongly with their party.
