It's worse then that. By law you cannot be asked to produce ID to vote in Wisconsin. ANYONE can go to the polls and vote in your place. One trick is they watch the rolls and see who hasn't voted, then just before the polls close they send in the frauds.
It shouldn't be harder to rent from Blockbuster then it is to vote.
It shouldn't be harder to check out a book at the Milwaukee Public Library (where 2 forms of ID, including a photo ID or an on-the-spot photo, is required to get a library card, and then the card is scanned each time a book is checked out) than it is to vote.
