When you only need to present a name (and possibly an electric bill) you can be bussed to 4 different precincts in the same city by organized crime labor.
If you have a voter ID with photo, the system can process the photos to look for duplicate registered voters (under different names).
But that makes too much sense. Better to spin yarns about flying to a city to vote twice.
Exactly. This whole “early voting” thing makes it all too easy to cheat. On Election day, there are lines and its difficult to get to too many places—time and distance work against the cheaters. But when you spread the process out over weeks, its all to easy.
