Prominent national Democrats have often claimed elections were rigged or stolen. They spent several years after the 2016 election claiming the Russians somehow hacked the presidential election.

We've documented a machine in this county that recorded 11,000 extra votes for Bush. In that county, there was counting Kerry votes for Bush... These machines are hackable. Link
