Speculation:
If Lin Wood "saw the numbers," then there absolutely is a copy of the unaltered election data they collected and stored.
Wonder if they hacked into the system and somehow got the votes collected before the digital fuckery.
When Q said the 2018 vote was protected, I am assuming they again had the unaltered votes stored, as a dry run of what they needed to be able to do to protect 2020. I hope as a part of the big reveal, they go back and invalidate a bunch of 2018 races (Senate, state houses) that did not come up for reelection in 2020.
