Just to make sure, anyone claiming that Republicans have never participated in any kind of voter sabotage in the last decade is factually incorrect. In fact, one of those who did just that even wrote a book about it called 'How to rig an election', after he got out of prison.
"After ten full years inside the GOP, ninety days amongst honest criminals wasn't any great ordeal."
