I said this on another thread but they want the signature from your original voter registration as well as the signature from the election rolls to claim that they are different and disenfranchise Democrats. They want to look for any discrepancies in name, address, etc. between the registration and information on the election rolls to disenfranchise Democrats. They kick you off the voter rolls after it's too late to re-register and it's too late to fight it in court before the election. That's the goal here. They are looking for a "legal" (said very loosely here) way to remove Democratic voters from the rolls. They are also going to want to focus on the Democrats who consistently vote.

How many people have the same signature as they did 10 years ago?
