How about if by "significant" I mean "has enough impact on elections to merit countermeasures that have been statistically shown to disproportionately reduce election participation [oh noes!] by brown people and people with lower incomes (regardless of race)?"
How about if by "significant" I mean "has enough impact on elections to merit countermeasures that cost at least tens of thousands of dollars per fraudulent vote, but probably hundreds of thousands of dollars per fraudulent vote?" Is there truly no more cost-effective way to spend that money on ensuring election integrity? Perhaps with little things like voter-verifiable paper trails that actually allow auditing of results?
Why, it's almost as if the oh-so-unfortunate side effect of minority and poor disenfranchisement is the purpose and "preventing vote fraud" is just the excuse. I'm sure Paul "our leverage in the elections quite candidly goes up as the voting populace goes down" Weyrich would have been heartbroken by that. https://www.youtube.com/watch?v=8GBAsFwPglw
I also looked through the report cited and found it remarkably light on actual facts. They make a big point of Maureen Erickson's cancellation for being a non-citizen in 2012 and her providing a Guatemalan address. They also note that she'd voted in 14 elections. Honestly, I'm surprised that they also included that the most recent of those was in 2008, 4 years before her registration was cancelled. So what happened in those intervening 4 years? Did this obviously Hispanic woman get thrown out of the country? Or perhaps she moved, married, emigrated, etc. and stopped voting in the US.
I'd classify that whole report as long on the fearmongering and short on the evidence.
Edit: I decided that was a unique enough name to look up, and lo and behold: "In fact, Todd Erickson said, his wife is an American citizen and while she does work as a missionary in Guatemala, her cancellation from Prince William County’s voter rolls in 2012 was a mistake resulting from the confusing voter registration system." and from the well-known lefty rag the Washington Times no less.
