The greater point, I think, is that everywhere else in American where I deal with the government I am required to present some form of ID. They even give you a list of a dozen or more valid IDs you can use.
However, arguably the most important interface with the government, voting is a place where I don't even have to validate I am who I say I am.
They don't really care who you are, they only care if you are allowed to vote. At least in theory, of course weird stuff probably goes on every year due to the size of the US.

In practice, voter ID schemes are used to disenfranchise citizens.
