Not to mention that there are a hell of a lot of actually-fraudulent voter registrations.
3 ballots out of hundreds of thousands in Hennepin County, Minnesota. This belief that there are all these fraudulent voters is a myth.
The only reason they do this is to suppress turnout for the Democrats. When people turn out at the polls, Democrats win.. pure and simple. That's why, for example, the SoS position is such a nasty battle here every election... because the GOP wants to make it very hard to vote in this state while the DFL wants to make it very easy, knowing that while it may increase fraudulent voting, it will raise turnout more than enough to make up for it. Besides, the people who would be voting fraudulently, here at least, would have to register on election day because, say, if you're a felon and ineligible, your registration is void.
So you fill out a registration form.. well, you need photo ID with proof of residence on it or a utility bill with your address and an already registered voter to vouch for you.
When fraud is roughly 0.08% of all votes in a system that makes voting easy and leads to the nation's best turnout year after year... I think I'll stick with that.
