This has been reported and he is already being investigated by State Board of Elections and so far they do not have any one by that name who voted. There is an article in the examiner dated 11/4/12.
Why would he use his own name?
he wouldn’t have used his real name
most likely a name of a comatose patient or deceased person... given to him by the dem leadership in the district (they need to keep it organized so they don’t get re-votes on the same name... tipping off anyone watching)
