Can normal citizens like me do that? Have you ever done that? Would I get photocopies or originals (which I'd read there, I imagine)? Would you recommend wearing a suit, rather than just "normal" clothes? Would I need to be armed with FOIA information? How would I find the local election office?
I'm up to doing that, but don't want to walk in there and be unsuccessful because I don't know what I'm doing....
As to your election office, see:

As to whether you can look at the Application for Registration forms, I called my local office and they said they would not show me the entire form, because it contains date of birth and DL number and SS number. But. . .
They will give me a list of names and addresses of those who have been registered on a mass scale. So at least these can be checked. The clerk would probably also let you photocopy at least the signatures on each form.
A copy of the voter registration form can be found at:

As to wearing a suit, I wouldn't think that would be necessary. Just be courteous, and persistent.
Hope this helps. Do all that you can.
