Why don't they stamp people with an indelible fluorescent dye when they hand them the ballot? It works in bars and clubs! It would prevent people from voting multiple times at different polls.
Great idea!! We may not want it, but wouldn't a National identity card solve most of this problem?
We are not worried about living voters showing up to vote once. We are worried about hundreds of thousands of Democrat operatives showing up to vote on behalf of dead people, felons in prison, dogs, cats, and purely fictitious people. I have heard that in some places in Ohio, there are more people registered than exist in those locations. Not just adults in those places, but all people.
We are also worried about the casting of hundreds of thousands of absentee ballots where hundreds at a time are in the same handwriting.
