VOTER IDs- I need information not a lecture

[underpants]

I know there are probably more important and timely issues to bring up but I got in a conversation about this last night and I really can't say that I understand it.

I think that the arguments goes that other than say check cashing or vagrancy or law enforcement issues voting is a RIGHT and therefore you can't be required to pay or do anything to participate. There also are some literacy issue being that there can't be a literacy test which an ID basically requires. I said last night that I was pretty sure that this had been decided by the courts across the board-no ID can be required for reasons stated above and going back to the poll tax and literacy tests.

Of course at my polling place here this morning there was a sign saying that you had to have ID and it listed what would satisfy that requirement and at the end it mentioned an attest statement but that was never mentioned in the rest of the posted flier.

Okay so help me to understand so I know in the future.

Why is it that no ID is still required?
