This is off of his wiki page - not the sturdiest of sources, and poorly written - small smile - but interesting still.
“”During the 2020 election, Raffensperger sought to PREVENT Georgia polling places from having printing paper backups of voter registration and absentee voting information in case polling places would struggle to use voter check-in tablets, called Poll Pads, which had been problematic in Georgia’s primary elections earlier that year. The tablets had caused long lines at polling places. Voting rights groups had requested paper backups to prevent a risk of chaos on election day in case the tablets failed.[16]””
*Emphasis mine*
We did have paper sign in sheets, at least in my county. But this is pretty suspicious if he didn’t want paper backups.
There’s your clue.
