Most voters use a paper ballot and fill in bubbles for an optical scanner.
These voter assist terminals are for voters that cannot fill out a paper ballot (such as do to severe Parkinson’s that prevent the voter from having the fine motor skills required to fill in a bubble on a paper ballot without spoiling the ballot.)
The FBI should be investigating, oh wait. they can’t be trusted either.
Might be being used for nursing home residents who think they are voting for FDR.
