Does anyone know if the integrity of the vote can be protected?

[Onlooker]

I know the Dems are going to have lawyers around, but what really can be done to protect the integrity of the vote. Are there things the Dems are doing/can do? Where are absentee ballots being stored? How do we know someone isn't preparing fake ones even as I write this? How do know that voting machines actually tabulate accurately?

1. Don't paperless machines violate equal protection?

If a state has mixed election systems, as many do, and some counties have voter veried paper trails while others don't, isn't this fundamentally unfair? Aren't voters who use such machines subjected to extra risk that their votes won't be counted if machines malfunction or are tampered with? Why would a legal challenge in such states not be allowed?
