In a clip from 2007, then Delaware senator Joe Biden advocated for election reform, saying that the federal government should obligate states to use the same machines because they would leave paper trails and thus greatly reduce the possibility of pulling off fraud.
“How are you gonna keep it from us being able to be in a position where you could manipulate the machines, manipulate the records. The one way to do that is—I think we should pass a federal law mandating that the same machines with paper trails be mandatory for every federal election. That will be a multi-billion dollar bill for the states because the states will have to make a choice then. They’ll have to make a choice whether or not they have two machines. We can’t mandate, as you know, state elections. We can’t tell the state of Delaware or Ohio or Texas what machines and what method they use to vote in their state elections. But we can do it federally. So in a nutshell I think we should be mandating that we have a paper ballot with the standardized machines, standardized requirements,” Biden said.
