Require proof of citizenship when registering plus picture ID and enter the info into a nationwide database.how would you have prevented it?So, you're ok with the 164 voting twice?
Do a search on every applicant through the database for duplicates.
Require proof through ID when voting.
Prosecute anyone who tries to vote more than once, even if Eric Holder doesn't want to.
I'm sure there are a lot of other ways as well.
so your solution requires a federalized database of voters and perhaps even some sort of national id. seems like a big ticket solution to a relatively minor problem.
and do you admit that a photo id alone would not have stopped the duplicate votes
