It stops the fraud machines.
Steep 1 register fake voters.
Steep 2 Make it hard to remove dead voters.
Steep 3 run buses around to poor neighborhoods under the scam theory that you are just taking people to vote. Pay each person $50 to vote.
Steep 4 take them to the booth give them a card telling them how to vote and a name they are to vote under.
Steep repeat take them to every voting booth in town and have them vote under many different names used in steep 1 and 2.
Voter ID laws shuts this down.
If you dont have voter ID in your state and you see one of these buses please film it and follow it around to make sure the same people dont vote in different areas if they do call the police.
But voter ID laws are not enough because fraud has now moved to mail in ballets. They must also be monitored to prevent fraud.
