National: Most U.S. voters use electronic or optical-scan ballots | Pew Research Center
While more than 46 million Americans already have cast their votes this year, 80 million or so more will be voting on Election Day itself. If you’re one of them, there’s a good chance you’ll use one of two basic forms of voting technology to record your choices: optical-scan ballots, in which voters fill in bubbles, complete arrows or make other machine-readable marks on paper ballots; or direct-recording electronic (DRE) devices, such as touch screens, that record votes in computer memory. Nearly half of registered voters (47%) live in jurisdictions that use only optical-scan as their standard voting system, and about 28% live in DRE-only jurisdictions, according to a Pew Research Center analysis of data from the Verified Voting Foundation, a nongovernmental organization concerned with the impact of new voting technologies on election integrity. Another 19% of registered voters live in jurisdictions where both optical-scan and DRE systems are in use.
