One would hope so. That doesn't mean that a group of democrats, in a smoky back room, wouldn't be forging signatures and casting votes. They'll stick to the ratio of the area so as to not raise any additional red flags. If an area went 65% democRAT, then that's how they'll cast the votes.
They do this after the actual election, because that's when they find the blank lines where someone had not voted yet. I am not certain how this coincides with absentee ballots though - if someone cast absentee and it hasn't been counted yet, what should be done with it if the forged signature is found on the voter rolls?
Soon they won’t have to resort to this ploy, as they’re seeding all the voting districts with enough muslim refugees and illegal voters to turn slim GOP majority districts into ‘RAT.
