You can get raw voter data from the local county or secretary of state, depending on where you live. You can get the name and address and which elections the person voted in and which party primary they voted in. That's about it from public data and you have to get it yourself. The states I've lived in would sell you the voter lists. For the demographic breakdown they're relying on polling data and no one will ever let you see the raw data for that.
