Nearly 40 percent of registered voters surveyed in a new poll are concerned about the integrity of the results of the upcoming presidential race, echoing warnings of electoral interference blared on both sides of the aisle.

Asked how they would feel if their preferred candidate were to lose next year’s election, 20 percent of those polled said they would be “not very confident” that the 2020 election “had been conducted in a fair-and-square way.” Eighteen percent said they would be “not at all confident” if their candidate lost, according to a USA TODAY/Suffolk University poll released Wednesday.

Just over half of respondents said they would be confident in the outcome of the election, with 21 percent of voters saying they would be “very confident” and 32 percent saying they would be “somewhat confident.” Nine percent of those surveyed were undecided or refused to answer.
