More than eight-in-ten registered voters (84%) say they are at least somewhat confident that people who are legally qualified and want to vote will be able to cast a ballot, while nearly as many (79%) express confidence that in-person polling places will be run safely and without spreading the coronavirus. About two-thirds (66%) say they are at least somewhat confident that after all votes are counted, it will be clear who won the election, while 62% are at least somewhat confident that people who are not legally qualified to vote will be prevented from casting ballots.
While most voters express at least some confidence in these four aspects of the presidential election, relatively small shares are very confident of each. For example, only about four-in-ten say they are very confident that people who are legally qualified and want to vote will be able to cast a ballot in the election, while only 22% say they are very confident that once the votes are counted it will be clear who won the election.
Voters are less confident that the nation will know the outcome of the election within a few days of Nov. 3 or that mail-in ballots will be delivered in time to be counted, with about half saying they are at least somewhat confident these will happen (50% and 52%, respectively). Just 13% of voters say they are very confident mail ballots will be delivered on time, while a similarly slim share (15%) say they are very confident the winner will be known within a day or two of Election Day.
Though majorities of Trump and Biden voters say they are at least somewhat confident that people who are legally qualified and want to vote are able to cast a ballot, Trump voters are more likely than Biden voters to say this (93% vs. 77%, respectively). And while only about a third of Biden supporters (32%) are very confident that people who want to vote will be able to, half of Trump voters have a high level of confidence this will occur.
