Will votes be counted accurately? What the public is saying

For more than 20 years, after each election, the Pew Research Center has asked voters whether they believed their vote and separately, votes across the country, were counted accurately. Around 90% of voters consistently said they were very or somewhat confident of this, and around 80% gave that response about the votes of their fellow Americans. The news media and political actors on both sides of the aisle are trying to scare voters about what could go wrong on Nov. 3, but most people are reasonably confident that voting will go smoothly in most places.

They are right.
