Oh, but they probably could. Residency is 10 (TEN) days and intent to make this your home. Oh, there's that pesky little detail about a WI Driver's Licence ID, but you can get around that by saying that you don't have one and providing the last 4 numbers of your SS#. THen you have to provide another form of ID -- a piece of mail with your name on it, bank account number, etc. Registering under a false name and using a piece of stolen mail will provide that.
Nobody will ever know until the postcard sent out by the County Clerk to check your address is returned as undeliverable. THis is the stupidest election system I've ever seen.
